JASPI Wood boilers

 

Jaspi has been manufacturing wood boilers for over 50 years.

Wood boilers were the first type of boilers to be used with central heating throughout the Scandinavia.

Our wood boilers have an exceptionally long track record for boiler service life, reliability and performance.

New technologies, like ceramic furnaces and gasification have taken the efficiency to new levels with ever reducing emissions.

 

Range

Our wood boilers can be divided into two groups;

- Wood boilers with a traditional, cast iron wood furnace

- Wood boilers with high efficiency, ceramic wood furnace

Everyday use

Jaspi wood boilers are reliable and simple to use.

All our boilers are fitted with thermostatic draft regulation and once set-up, works automatically without user intervention.

Econature gasifying wood boiler has a fan which starts and stops according to the boiler temperature, always running the boiler at the optimum temperature.

Weather you burn wood, large wood pellets or heat logs, the best results are achieved when the fuel is dry.

 

Technical

Jaspi wood boilers can run on logs, large briquettes, blazer logs or compressed fuel logs.

We do not recommend newly cut, unseasoned wood to be used with our boilers, and most definitely not wood that has been treated with Creosote or tar like for example railway sleepers and electricity poles.

If your wood fuel is of highly variable quality and moisture level, we recommend the YPV40 traditional cast iron wood boiler over the ceramic boilers.

This is often a better option for example farm and light industrial use. 

For more consistent quality fuel, the ceramic Ecowood 25 and Econature 40 will produce exceptional results.

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

All our wood boilers must be connected to a thermal storage tank. 

Domestic hot water and heating for radiators / underfloor heating are taken from the thermal tank.

 

The thermal store is also used if the heating system is expanded to other heat sources like solar and heat pumps.

Heating controllers

Between the wood boiler and the thermal tank you need a Termovar loading unit. It incorporates a circulation pump, thermostatic valve, by-pass valve and a non-return valve.

It is controlled by the boiler (Econature) or a flue gas thermostat (Ecowood 25 & YPV 40).

Termomix mixing valves are used between the heating circuit(s) and the thermal tank. They will control the heating flow temperatures as well as preserve the heat and thermal layering within the thermal tank.
