Right, I'm going to have a biomass boiler fitted. Going for one of the Effecta range.
What I can't work out, is it best to have a thermal store that is then pumped to a separate DHW cylinder for mains pressure, or a tank with a stainless heat exchanger fitted?
Looking at 1000-1500ltrs store on a 25kw pellet boiler.
Its a bit of a head scratch working out what the best way of running this type of system is!
Any other ideas or thoughts?
These are my thoughts...
10 things your installer won’t tell you about your pellet biomass boiler before you buy it....
1.We may overspec or underspec your boiler.
2.The biomass boiler will likely breakdown frequently.
3.The boiler will require “considerable more time and effort to ensure it runs efficiently and gives long service” compared to a gas boiler or oil boiler.
4.The weekly checks and clean-outs you are required to carry out will not prevent breakdowns from occurring.
5.When your boiler does breakdown, your building will be without heating for more than a few hours because we don’t have an engineer in your area.
6.When things go wrong – and they will – we will blame it on the quality of the fuel you have purchased to burn in the boiler, not the quality of the boiler and parts.
7.The electrical items on your boiler, only have a 12 month guarantee on them but some, such as the heat gun, will likely fail frequently.
8.The service contract is very expensive because we know you will need to call us out a lot.
9.Because the boiler will likely be manufactured abroad, we will not feel the same sense of responsibility to put things right as we would if we were the maker.
10.When you decide it really does not make sense to keep throwing good money after bad, we will not buy back/sell on the biomass boiler for you.
Finally why do you think you need thermal storage/buffer/ accumulator tank with a pellet boiler?
Does the manufacturer recommend one?
And remember to keep a stock of woolly jumpers on stand by for when it breaks down.
