JASPI Multifuel boilers

 

Our range of true multifuel boilers can run with up to six different forms of energy simultaneously.

They offer the ultimate flexibility when choosing the heating system and even further, they can be changed to use a different form of fuel at any point.

For the user, Jaspi multifuel offers the convenience of an automatic burner boiler, like an oil boiler, and the economics of a traditional wood boiler - all in one unit.

To further increase the choice of fuels, all our multifuel boilers have a built-in electric backup heater which can be used to boost the power output when the heat demand is high or as a sole source of heat when less heating power is needed.

This electric element can also be powered by solar photovoltaic panels, water- or a wind turbine.

In short, for example a Duo 2 boiler can use; Oil, Wood, Solar thermal, Solar photovoltaic, wind and mains electricity simultaneously.

With this kind of flexibility the boiler can run for example with solar and wind as main heat sources and the wood and oil are only for a back-up.

We have customers who are running their boilers this way, effectively running their heating for free.

 

Range

Our multifuel boilers can be divided into three groups;

- Twin furnace boilers with a traditional, cast iron wood furnace

- Twin furnace boilers with high efficiency, ceramic wood furnace

- Twin furnace ceramic boiler with vertical plate construction suitable for pellet burners

Everyday use

Jaspi multifuel boilers are extremely simple to use.

Most commonly they are used as a normal oil or gas fired boiler during the week and at the weekends the logs are burned to reduce the oil consumption or, if connected, to charge an external heat store.

The user does not need to do anything when changing from oil to wood, simply light up the logs and when the wood burner is at the running temperature, the oil burner automatically shuts down. 

If the boiler is connected to the solar, wind or hydro power, these will have the priority and the oil and wood are only used as a back-up.

Technical

Jaspi multifuel boilers have two burning chambers side by side, one for logs, large briquettes, blazer logs or any other compressed fuel logs, like peat.

The second burning chamber is for the burner. This burner can be for oil or biofuels, gas, LPG or pellets.

As standard our boilers are delivered with a Riello oil burner.

These boilers need only one flue which must be rated to class 1 for solid fuel. Balanced flues will not work as the boilers need a good draft to work.

Our multifuel boilers have a large internal water tank so they can be connected directly to the domestic hot water system and radiators / underfloor heating without a need for a hot water cylinder or a thermal storage tank.

If logs are used frequently, it is recommended that the boiler is connected to a thermal storage tank. This increases the capacity of the stored heat and the wood boiler's efficiency.

An external thermal store should also be used if the heating system is expanded to other heat sources like solar and heat pumps. (apart of DUO 1 & 2 boilers, see below)

 

DUO 1 & 2 with SOLAR

Our DUO 1 & 2 multifuel boilers can be fitted with an additional solar coil. This enables the boiler to be connected directly to the solar panels without the need for a thermal tank.

Recommended panel sizes are 2.5 sqm for DUO 1 boiler and 4 sqm for DUO 2 boiler.

 

Ready for heating & hot water

All our multifuel boilers are fitted with a domestic hot water coil and Termomix heating mixing valve.

The powerful domestic hot water coil will produce mains pressure hot water as and when it is needed.

Termomix heating mixing valve connects directly to the heating flow & return. This valve can be fitted with Automix temperature controller, for example CT constant temperature controller for underfloor heating or Automix 10 weather compensated controller for radiators.
