A new highly efficient woodburning stove that incorporates a boiler to generate hot water for central heating – and can be connected directly to a sealed heating system as well as plumbed conventionally on an open system – has been launched by Broseley Fires.
Like all stoves in the company's eVolution range, the new eVolution 8 combines eco friendly features with a contemporary design and the latest in stove technology.
But what makes it particularly suited to 21st century living is the fact that it incorporates the Safety Cold Water System (SCWS) which has been pioneered by Broseley Fires.
SCWS enables Broseley’s solid fuel boilers to be fitted onto new or existing sealed central heating systems, including combi boilers, without the need for additional unsightly pipework and controls to vent the boiler. The eVolution 8 system can easily link up with other boilers or heat sources such as solar panels or ground source heat pumps through connection via a thermal store or low loss header.
Standard woodburning boilers that don't have SCWS have to be fitted on a traditional open vented system because once the stove is lit there is no way of shutting down the appliance quickly to take the heat away from the water in the boiler. Should there be a problem such as a central heating pump breaking or a blockage in the system, the water would build up in the boiler and overheat (which means the water would boil). This could cause a pressure build up which, without an extra feed and expansion on the system, could cause the system to rupture and even explode.
A key feature of the efficient SCWS system is that it prevents the water in the boiler jacket from reaching boiling point by transferring heat away through a secondary built-in quench coil. This means the heating system or stove can never become over pressurised so there is no need for a safety failure feature on any part of the open system, including the feed and expansion tanks. One major benefit of this is that if a combi boiler was used as well there would be no need to have the hot water tank in the loft because the combi would provide this water direct.
The eVolution8 boiler stove was developed by Broseley to meet the growing demand in Europe and the UK for highly insulated, air-sealed housing and sealed heating systems. The system means that, for the first time, a wood-burning boiler can be seamlessly integrated into an existing sealed heating system, with no additional expansion tanks or pipework.
The eVolution8 is a free standing stove which is designed to maximise convection heat output from all working surfaces. The huge 400mm x300mm glass panel has a door designed for a crisp, quality closure and is kept clear with a pre-heated air wash offering high visibility of the flames. The slimline design is finished in grey painted steel and has a nominal heat output of 11kw, 8kw to water and 3kw to room, and is one of the most efficient in the industry operating at 83 per cent efficiency.
Says Product Development Engineer Tristan Johnston: "The modern home demands a good-looking, highly functional heat source that combines contemporary design and solid construction with the very latest technology and maximum efficiency. The eVolution 8 fits the bill perfectly and was developed with this growing market in mind. It gives just the right amount of heat into the room while meeting the hot water/heating demands as a secondary source of heat."
He adds: "All eVolution stoves are highly efficient and clean burning, and with us able to offer the choice of free standing, inset or boiler stoves, there is now a model to suit every home."
Because of its unique features, the Broseley Fires Safety Cold Water System can only be fitted and maintained by engineers who have undergone specialised training. This training teaches engineers how to install not just a SCWS system but the extra safety features as well. These include the secondary quench coil, a thermal safety valve, a safety blow off, a three-way valve, expansion vessels and alarms.
All installers of the SCWS have to be trained by Broseley Fires on the system and how to install its additional safety features. Broseley provides this training free of charge to affiliated installers. Also, the eVolution 8 is subject to reduced VAT of 5% to end users, part of a government incentive scheme.
