18kW Warmflow Biomass Boiler, Cambridge


18kW Warmflow Biomass Boiler, Cambridge

Summer 2015

18kW Warmflow Biomass Boiler

5 Years

Project details:

Andrew and Kathryn’s recent Energy Performance Certificate (EPC) indicated that their current heating system was not very energy efficient. The under sized existing electric boiler wasn’t meeting the family’s heating and hot water requirements. As the house wasn’t being heated properly, there was a risk of mould and damp problems developing.

During the solar installation on the roof of their family home, Andrew asked if we could provide a solution to update their current heating system. Roly discussed the possibility of installing another wood burner with the existing electric boiler or a Log Gasification boiler but due to space and on-going demands this wasn’t a suitable option. An Air Source Heat Pump could have been a possibility but Andrew wasn’t keen on upgrading all their radiators.

There was an outside space almost hidden behind the family home where the solar inverter was placed; having an external biomass boiler in the same area was agreed. This would give good connections between the boiler, hot water tank and radiator pipe with minimum disruption.

Roly calculated a 18kW biomass boiler was required to meet the family’s heating and hot water demands. With a reputation for quality and reliability, high energy efficiency and weather proof casing, an external Warmflow Biomass Boiler was recommended.

With the built-in 120 kilogram hopper, Andrew and Kathryn can expect to refill the boiler with wood-pellets every 7 to 10 days depending on heating requirements. The convenience doesn’t stop there as the system has automatic burner cleaning, de-ashing and modulation power output all at an affordable price.

Andrew was particularly impressed with the user-friendly controls that let him know when the pellets are running low, when the ash box requires emptying, and that everything is okay with the system in general.

Andrew and Kathryn will look forward to enjoying a warmer home, with lower heating bills and a boiler that provides an income every time it runs!


“We have for several years been dissatisfied with the heating of our property. It was provided by an electric boiler charged overnight on Economy 7 and heating the rooms through conventional water filled radiators. The capacity of the boiler meant that the water temperature in the radiators had to be kept low in order to provide ‘heat’ all day without having to ‘boost’ the boiler with expensive day rate electricity. As a result of our regime our heating costs were low albeit that the house was cold! We provided additional heating to our lounge by the use of a coal/wood burning stove which since one of us retired was in use all day.

We discussed at length our heating requirement with Eco Installer following an EPC assessment and considered all the options available that would qualify us for the finance available through the Green Deal’s RHI (Renewable Heat Incentive). As a result of those discussions and considering the benefits and financial considerations of replacing our existing system we decided to place an order for a biomass boiler fuelled by wood pellets.

Eco Installer recommended a Warmflow which has been designed to stand outside without the need for a covered area to house the boiler. The installation was completed in a week as planned; we are looking forward to warm house this winter! We have had already seen benefits gained through the system being ‘pressurised’ resulting in a significant increase in pressure in the hot water system seen in our showers and hot water taps.

We have taken delivery of a pallet of bagged wood pellets by a supplier who was able to offload next to our covered storage area so we are all set for the winter.”

Solar for School


Solar for School

Your school can now choose ‘green’ solar power and reduce electricity costs, whilst lowering its carbon footprint.

As energy prices continue to increase annually, Renewable energy is on the rise. Every school has the potential to generate its own energy. As most schools have a large roof, solar panels are the ideal choice. For those that really want to be green there are other alternatives such as Biomass Boilers or Air Source Heat Pumps.

The benefits of having Solar Panels installed:

Reduced energy bills – Solar Photovoltaic (PV) panels will reduce your schools electricity bills, allowing you to spend more money on education and resources. Solar Panels can generate electricity for decades offering substantial savings.

Revenue generations – The Government introduced the Feed-In Tariff (FiT) which allows schools to receive a fixed income for electricity generated annually and for any unused electricity exported back to the grid. Schools can enjoy a steady income over a 20 year period with Solar PV. As an example, most schools can accommodate a 25kW Solar PV system, which could generate an annual income of £3,435 at the current tariff rates. (Please check the OFGEM website for current FiT’s.)

Reducing CO2 emissions – Solar PV will significantly reduce your school’s CO2 footprint by several tonnes, each and every year.

Education and engagement – What better way is there to show pupils the benefits of renewable technologies than taking action and demonstrating the benefits though a working example. This will create direct engagement and will also inspire the local community to take action to address climate change.

Replacement boilers for schools – Kitchen areas often have excess heat that is extracted mechanically; this could be re-used by a heat pump to give ‘free’ hot water for cleaning, cooking etc. Ageing boilers become expensive to run and maintain; upgrading to a Heat Pump or a Biomass Boiler can reduce emissions and fuel bills whist also providing a welcome income from the Renewable Heat Incentive.  Please contact us on 01353 669000 for more information.

Planning Permission

Planning permission is not usually required for the installation of a solar panel system on the roof of a property or as a small (approximately 6 panels in total) stand-alone installation.  Please refer to the East Cambridgeshire District Council ‘Planning for Renewable Energy’ document for more information.(ECDC Planning permission for Solar)

UK Power Networks

UK Power Networks provides the information for power in all the homes and businesses in our area (please see print out of map). Currently UK Power Networks have limited single phase installations to G83 or 3.67kW per phase. This is due to grid capacity at Burwell Main Grid, and there is no date forecast for when this will change. Because of the amount of solar farms local to us, a limit of a 4kW solar installation has been set. 4kW is certainly adequate to produce 70-80% of a family home needs. If you wish to generate in excess of this please ask a member of our team for information on G59 3 phase installations.

Microgeneration Certification Scheme (MCS)

MCS is a mark of quality and demonstrates compliance to industry standards. Property owners need to use a MCS approved installer to enable them to apply for the Government incentive the ‘Feed-in Tariff’ (Fit). Eco Installer are MCS approved having held the qualification since 2011, ensuring all our solar installations meet the high standards set. For more information please visit

Project details:
Existing customers Andrew and Kathryn gave us a call to find out the suitability of a solar Photovoltaic (PV) installation on the roof of their garage. Roly visited the property in Mepal, Cambridgeshire to carry out a site survey and went though the different options available.

Upon arriving at the family home, Andrew explained that Kathryn wasn’t fond of a solar installation but was happy to explore different ideas. Roly questioned the possibility of installing a solar array on the roof of the bungalow which had a larger space and was more south facing than the garage. The more south facing the panels are, the more renewable electricity produced.

Roly explained that the solar panels can be installed on top of the roof titles as traditionally seen or installed ‘in-roof’. In-roof systems are becoming increasingly popular on new builds but they are just as suitable for retrofit installations. In-roof panels are designed to fit seamlessly into a roof like normal roof tiles. Unlike conventional PV panels, the tiles form part of the roof itself. Kathryn and Andrew liked the in-roof option and were keen to explore this further.

Following the site visit, Roly sent Kathryn and Andrew a design and quote for an in-roof solar system using Sunsolar Black Mono Crystalline Panels which carry a 25 Year Manufacturers product warranty and a 25 Year Linear performance guarantee. Kathryn and Andrew were pleased with the information received and were happy to place an order with us.

Our Engineers removed approximately 1,200 tiles to make room for the solar panels, the installation took our engineers just four days to install. Following the installation Mike, our in house electrician installed a Solar iBoost which diverts spare energy from the PV array into domestic hot water for further savings.

Kathryn and Andrew are delighted with their Solar PV installation, the panels fit in really well and look almost like Velux windows.


“We wanted to reduce our dependency on fossil fuels and as The Barn was only on mains electricity we thought that we should look into the feasibility of installing Solar Panels. We called into Eco Installers’ showroom in Sutton, Ely to just make initial enquires with a local installer who we have used for other smaller work. We had a quote from a national installer and had used the government backed web sites to determine possible costs and payback periods.

Whilst discussing the system I (Kathryn) did have to confess that I really did not like the majority of solar panels I have seen on roofs and did not want them on the house roof but would agree to them on the garage.

When in the showroom, Roly pointed out that the table we were sitting at was made from a Solar PV panel and this did not look at all like the ones I was talking about but was a black panel which did look much better than others that I had seen. I also did not like the panels sitting on the tiles of the roof but it was explained that it was possible to position panels recessed into the roof, by removing the tiles and fixing trays onto the rafters and then the panels would fit in the trays. I was feeling a bit happier so Andrew and I arranged for a home visit.

It soon became apparent that the garage was not ideal position or construction and would require the cables from the solar panels to be put in a trench to connect to the grid at the electricity meter in The Barn. That would involve a significant increase in the installation cost. We asked for a quotation for installing the panels on the garage and on the main roof with the panels recessed.

We appreciated the advice given by Roly and Mike and their patience shown while we came to an acceptable solution. In the end we agreed that the best option was to fit the panels to the main roof with all 16 panels fitted in portrait orientation and in a single string.

Installation went ahead as planned but was interrupted by high winds, the team worked well together and completed in good time. We give special mention of how well that was done, thanks.

As I hope you can tell we are very pleased with the system we have had installed by Eco Installer. I think we all agree the Solar installation actually adds to the appearance of The Barn.”

Ventive – Breathing Fresh Air back in to Your Home


Ventive – Breathing Fresh Air back in to Your Home

Ventive – Breathing Fresh Air back in to Your Home   

Mould problems? Stale air? Condensation? Family members showing signs of eczema and asthma? Concerned about Dust mites?

Poor ventilation could be a cause for all of these.

Many customers ask us for a solution to these problems, in the past we didn’t have a solution but now we do:

‘Ventive Passive Ventilation with Heat Recovery (PVHR)’

PVHR prevents the occurrence of condensation and mould in homes and commercial properties, keeping the indoor air free of pollutants such as carbon dioxide, Volatile Organic Compounds(VOCs) and excess humidity. The system brings fresh filtered air in to the property; it’s like a Brita water filter but for the air with the added benefit of heat recovery.

It’s an easy installation and the price starts from as little as £499.00 (plus access and installation), a small price to pay to ensure the health and wellbeing of your family or staff.

Who is the Ventive system suitable for?

Ventive’s PVHR system is perfect for domestic properties, both privately owned or rented, it is also tremendously beneficial for schools, hospitals, sports facilities and a wide range of commercial buildings.

The system can be retrofitted or included in the design of new build projects.

How does the Ventive system work?

The Ventive PVHR system is driven by two natural forces, air buoyancy and wind (active from very low wind speeds) to create a flow of air within the interior of the building, ensuring greater than minimum standards of air quality are achieved and maintained.

Natural air rises through the PVHR vent, the heat is then collected by the highly efficiency heat exchange and then simply returned back into the property at low level recovering up to 95% of the heat (please see below image). This is achieved passively without the use of electricity.


Passive Ventilation with Heat Recovery for Existing Properties

The simple system can easily be integrated in existing buildings.

The ‘Ventive S’ single PVHR unit is retrofitted into existing chimney stacks, replacing the chimney pot with a cowl and cassette that features an innovative, patented and incredibly efficient heat exchanger. This system takes approximately half a day per unit to install, depending on site conditions and access.

The ‘Ventive S+’ can be retrofitted without a chimney being present within the building. Utilising an integrated duct system, Ventive S+ fits neatly between rafters and seals to the existing roof finish, allowing easy installation of multiple or single units. This system takes approximately 1 day per unit to install, depending on complexity.

Passive Ventilation with Heat Recovery for New Developments

The PVHR system is also ideal for new builds. Property designs are becoming greener with energy efficiency in mind. Insulation is a high property when planning a new home, new developments are being built so air-tight and ventilation is often an afterthought.

The ‘Ventive F’ system is whole house Passive Ventilation with Heat Recovery solution. The Ventive F naturally removes stale aim and VOCs from every room and supplies fresh, pre-warmed air into the house.

All Ventive systems are designed for continuous twenty-four hour ventilation, for the supply of fresh air and the extraction of stale air independently, into and from each area of the home.

PVHR Maintenance:

Minimal maintenance is required as the Ventive system has no moving parts . A quick dust of the grills every month and the maintenance is complete.

The Ventive solution to condensation and dampness

Ventive’s passive ventilation with heat recovery unit is designed to provide a property with all the fresh air that’s needed at home with zero running costs and virtually no heat loss.

With the Ventive system you can have both an energy efficient and healthy home that breathes naturally. Once the system is installed you can be reassured that you will be breathing pre warmed fresh filtered air all day long.

What does a typical PVHR installation look like?

Project details:
When exhibiting at the Haddenham Steam Rally, we met Les who was interested in a solar installation on his narrow boat at Earith Marina and also one for his Son’s house in Somersham, Huntingdon.

Upon visiting Graham’s (the son’s) home, Graham explained that the house had subsided resulting in an un-level roof. Before the property was underpinned Graham took full advantage of the situation and had a ground source heat pump installed to contribute towards the families heating and hot water demands.

Graham intended to have a Velux window installed in the roof so asked us to leave a section of the roof clear. Roly carried out a site survey and felt with careful planning the solar installation could take place.

Roly calculated 16 panels could fit comfortably on the roof producing 3,613kWh of energy per annum. Roly’s design showed 10 panels on the left side of the roof and 6 on the right to leave space for the new Velux window to be installed. We recommended ‘Perlight Delta Black Mono Panels’ which look great, come with a 10 year manufacturer’s warranty and a 25 year performance guarantee for the panels.

Les was pleased with the quote and design received. Mike, Will and Dayne completed the installation in just over two days. Mike, our in house electrician will be going back shortly to install a Solar iBoost which diverts excess energy from the PV array into domestic hot water for further savings.

We estimate Graham and his family will be approximately £800 per annum better off with income generated from the Feed-in Tariff, electricity exported to the grid and annual electricity savings.

“Despite having a very tricky roof, the panels are perfectly straight and look great. Mike was very thorough and took his time. Throughout the installation Mike explained what he and the team were doing which was very useful.

I am delighted with my system and enjoying solar electricity. Mike and the engineers did a fantastic installation; I have already recommended Eco Installer and will continue to do so.”

15kW Panasonic Air Source Heat Pump

Project details:
Sam contacted us when developing his new family home in Somersham, Huntingdon. He explained that the property was off-grid and was keen to have an energy efficient heating system installed allowing him to generate his own clean energy.

Sam brought the architects plans to our office in Sutton, Ely to find out the suitability of a renewable installation for the new build and to see how he could financially benefit from the uptake of renewable heating.

After giving Sam advice on different technologies available, Roly and Shane arranged a visit to the property in the early stages of development to discover which heating system would be most suitable to meet the family’s heating and hot water demands. Sam explained that the main necessities for a renewable heating solution were reliability, automation, low noise levels and ease of use.

Roly carried out a complete site survey and a heat loss calculation of the 4 bedroom property. From the requirements out-lined by the family and the information from the site survey, it was decided that the installation of a heat pump was imperative for economical heating to be achieved.

We recommended a Panasonic Aquarea Air Source Heat Pump to meet heating and hot water requirements. The family can be reassured that with the sophisticated “T-Cap” technology they will have consistent power all year round creating a long-life solution with high energy savings.

Our heating engineers positioned the Heat Pump neatly in the back garden and the High Gain Cylinder and Buffer Tank in a cupboard in the customer’s home. Once the Air Source Heat Pump was firmly in place, we were able to integrate the system to enhance the capabilities of the properties newly installed under-floor heating.  Whilst our engineers were on site, they carried out the first fix heating and plumbing for the bathrooms.

The family are now living in the property and benefiting from constant heating and hot water. As the Aquarea heat pump is MCS accredited, the family is reaping the benefits from the Renewable Heat Incentive (RHI) for every kWh of renewable energy produced.

Panasonic’s Aquarea range of air source heat pumps deliver tangible results for homeowners thanks to its quick payback in purchase and installation costs, along with enduring savings in energy and heating bills. To find out more please visit the Panasonic Website or give us a call on 01353 669000.
