18kW Warmflow Biomass Boiler
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.”
