PelHeat now offer custom made insulation covers for biomass or wood pellet, chip, log or straw bale boilers. Made from woven glass fibre with a silicone rubber coating and aluminium faced glass wool insulation the Boiler Cosy provides excellent insulation and is very durable.

PelHeat specialise in promoting UK manufactured small scale pellet production solutions.

PelHeat now offer the Biomass Boiler Cosy which is made in Great Britain for homes and businesses to reduce their biomass heating costs.

PelHeat have owned their Tatano biomass pellet/log boiler since 2008. It was clear from the start that some heat was being lost through the front door of the boiler. However only recently when an infrared heat gun was used on the boiler was the extent of the heat loss made clear.

“We waited until our biomass pellet boiler was up to temperature and had been operating for several hours, we recorded a door temperature of over 200 degrees Celsius!” said Chris Scott, owner of

The design of the Tatano biomass pellet/log boiler is quite common for biomass boiler heating systems. The hot exhaust gases from the fire are directed by the door through the horizontal heat exchanger tubes. While the materials used on the door lining are fire and temperature resistant they are not the best materials for insulation.

“A door temperature of 200 degrees Celsius is obviously taking a lot of energy out of the exhaust gases which should be heating the boiler through the heat exchange tubes,” said Chris Scott, owner of

Unlike gas and oil boilers most biomass boilers are located in cold outbuildings and sheds due to the extra cleaning and maintenance that is required. Therefore this cold room temperature will put even more load on the boiler pulling heat out of the door.

“We thought we could come up with a practical solution to this issue, so we developed the Biomass Boiler Cosy and the results have been very successful,” said Chris Scott, owner of

Once the Tatano biomass boiler was at operating temperature fuel consumption readings were taken with and without the Biomass Boiler Cosy. The results were that the Biomass Boiler Cosy reduced fuel consumption by an impressive 13.9%. Over a 24H period this means the Biomass Boiler Cosy saves 9.84 kg in premium grade wood fuel pellets.

“We currently pay £200 per tonne for wood pellets so a 9.84 kg reduction in fuel consumption is saving of £1.97 for 24 hours of heating,” said Chris Scott, owner of

Each Biomass Boiler Cosy is custom made to fit the client’s biomass boiler. The cover can be designed to fit pellet, chip, log, briquette and straw bale boilers.


Started back in 2008 PelHeat produced one of the first mobile pellet machine prototypes. PelHeat now provide a range of high quality UK made small pellet mills and pellet plants to produce a wide range of materials into pellets. They offer a material testing service and also provide a range of information on the process of how pellets are made and how to purchase fuel flexible pellet combustion systems such as pellet stoves and boilers.
