Working way through various grades of coal. Light boiler with Polish coal, then use red flame. These work out very expensive. Trying to top up with slack ? beans these throw out good heat. Only problem is can only put on when set temp reached because of smoke. ( not in smokeless area) Also appears to be more tarry than other fuel

Tried turf - too ashy and needs constant refills. Also tried logs didn't really work - by the time put last logs on clothes were full of smoke. Didn't last long.

Just wondered what other peoples experiences are and what is most economical fuel to use

Sorry im no expert when it comes to fueling such boiler, when I do come across them the homeowner usuall has a ready supply of hardwood fuels locally.
do you mind me asking your reason for installing.

We are in a house built 10 years ago with oil ch. Cost over €2,500 per year and a bag of coal for living room fire each week. Ch was only on about. 8 hours a day. House was cold and draughty.

People locally started installing Polish slack boilers and said they only cost € 30 per week to run. We researched them and visited people who has installed them. We decided to go for one with several safety devices and minimum temp return pipe rather than basic boiler.

We do not have a supply of hardwood locally and our trial of local logs was not a great success

Ran it yesterday on coal topped with red flame and finally black boiler beans. One filling lasted nine hours and it does not seem too tarry this morning. I estimate this will cost us about €240 per month in winter. There is little saving but we have constant heat.

We have 4 bedrooms, living room and conservatory. We have 22 radiators. The boiler was installed a year ago. The temperature within the house is controlled by radiator thermostats. The house is very warm. At the start it was too hot but we now have it very comfortable. The boiler uses about 24 to 30 kgs of fuel per day. We use a mix of coal, redflame(smokeless) and back boiler beans. Cost range from 22 to 40 cents per kg. Unfortunately we can't burn the cheapest all the time because of the amount of smoke generated by the beans particulary in wet heavy weather. We have found putting asmall amount of beans on at a time is best. We burn it 24 hours per day. It will keep going for up to 5 days but then needs ashes removing. Daily riddling only removes a small amout of ashes.

The boiler is quite messy and requires cleaning about every 7 to 10 days. Couldn't do without it now but don't like mess. The model is Moderator Unica Sensor. I think it is 25kw model. Happy to help.

Hi Mary,

Hows the moderator going for you, i'm thinking of installing the same boiler and using mainly turf. i live in the sticks so smoke isn't an issue.
