Boiler choice
Which boiler should I choose?
There are so many different types of boilers, how do I know which boiler is right for me?
When advising customers on selecting the right boiler w go through our 'over the years' developed checklist.
Roughly for every 100 square meters a building will need around 10-12kW of heat produced by boiler. So a 240 square meters house will need a boiler of around 26kW power output.
-
We start by establishing the property size, this can be in feet or meters square, simple measure of outside of the building is enough.
-
Is the boiler to heat water or is a stove or fireplace insert sufficient?
-
What fuel is the boiler most likely to burn?
-
Is someone around to monitor the boiler or is fully automated multi fuel pellet boiler more suitable?
For all boilers above sizing is correct, however for manually loaded boilers we advise to oversize the boiler and take advantage of large fire box sizes.
For example, DWBi 20kW boiler has a fire box volume of around 65 liters whereas 30kW boiler this measures 130 liters. The extra volume can be used to extend burn duration, allow for bigger logs to be fed, less processing and ability to feed shrubs or other bulky fuels without having to refuel the boiler every couple of hours.
There is a point where boiler is too big, it will then sit smoldering for long periods of time and eventually tar up internally. With an addition of a buffer tank a fill a day is achievable whilst maintaining clean burn. For example, an average 240m2 home can be fitted with DWBi semi automatic manually loaded 50kW boiler and a 1000 litre hot water storage buffer tank. On average one fill a day should produce, during cold months and if filled with seasoned hard wood, 24hr worth of heating. This is based on temperature being set at 21deg C and clock working with zoned thermostats over 11-12 hours cycle.

Pellet Boiler - Automatic boiler
This boiler range is the most technically advanced available on the market. Their use is directed primarily to those users who desire the convenience that pellet fuel offers. As a general rule the hopper can be filled on a weekly basis and will require no further input, (except to occasionally cast an eye to ensure all is safe). Some models have the added ease of self ignition.
They are suitable for both domestic and non- domestic usage and are available from 15kW right up to 150kW
The primary intended fuel is wood pellets although it is possible to use coal, oats, logs and waste wood and lignite.
As with all our boilers each and every component is sourced and assembled within Europe from reputable manufacturers.
We are delighted to have this range of boilers available as we are confident they have been tested thoroughly and perform to the maximum possible standards.
Semi Automatic
This popular range has electronic controller allowing the user to program the boiler for maximum efficiency. A fan provides the added bonus of allowing slow combustion times resulting in less fill up times for even up to 18 hours.
They are suitable for heating domestic and non domestic premises with a vast range of sizes available, from 9kW right up to 100kW.
This boiler range can be fed using a number of high energy fuels including cardboard, coal, turf, logs, pallets, through to pellets, grain
These boilers are well finished machines and their features advanced and evolved throughout the years.
We are happy to promote this line of boiler, safe in the knowledge the manufacturers have been producing them for decades and are the most popular in Europe due to their durability, high efficiency and high performance.
Manual
These are a basic range of boilers. They have a no frills approach to heating and contain all the necessary elements needed to heat domestic or commercial premises at a very attractive price. They are available in a range of sizes from 5kW to 50kW.
Because they do not have an electronic controller they relay solely on good strong draw in producing their output.
They are simple and straightforward to operate with few moving parts.
These can be installed in an environment where there is no electricity, off grid.
They do of course, like all the boilers we supply have all relevant EN numbers and are manufactured using high grade steel.
Wood burners - Space Heater
A space heater is designed for heating industrial premises, commercial buildings or halls, factories, warehouses, workshops, open floor spaces and simillar.
They are available in 30, 35, 50, 70 and 100kW
These machines are very efficient and will extract maximum heat possible out of most fuels. They are very economical to run as operating costs are low adding that off cuts, cardboard and other cheap fuel can be used. Room temperatures can drop below 0 C so these space heaters are ideal for everyday work time 9-5 use where the premises are vacated at night or indeed for occasional use where it might be a couple of weeks between uses.
