What are your views on the mandatory installation of new condensing gas/oil fired boilers. Are these boilers really saving the householder/building owner money?
I am sitting at home at the moment waiting on a plumber to have a look at our oil burner. It is the old type with the flue going up through the garage roof. I can actually see the flame through the top of the boiler at this stage so might just replace it with a condensed boiler, Does anyone have a suggestion as to which boiler is more efficient and apprx how much it costs, and roughly how much would I be looking at to get one fitted, I have read the above posts and find them interesting but if anyone has any basic info I would appreciate it, Thanks Salaried.
Sorry to be so thick - but what do you mean by "system controls".
For a list of the most efficient boilers on the market, go to You will see that Grant Vortex model wins the top 20 on the market. It is by far the best boiler. If cost of boiler is an issue, then my second choice would be Grant Euroflame Condensing boiler.
With regard to your existing boiler, make sure that the flue is sealed before using it again, otherwise you are in danger of carbon monoxide poisoning. Also if you install a new condensing boiler, ensure it is commissioned and installed to the manufacturer's & OFTEC's specification and that the Boiler Passport is filled out with a printed flue gas analysis attached to it. As of 1st September 2010, Grant, Firebird and Warmflow will no longer accept any warranty calls without it.
Cost of boiler:
Grant Vortex 26kW Boiler House Model: €1,100 Incl Vat
Low Level Balanced Flue Kit: €140 Incl Vat
Grant Vortex 35kW Boiler House Model: €1,200 Incl Vat
Low Level Balanced Flue Kit: €160 Incl VAT
Plume Diverter Kit if required: €200 Incl Vat
You will also require remote acting fire valve, condensate pipe, insulation (thickness equal to pipe diameter & armaflex sticky insulation on joints), frost stat if in unheated garage, AAV's (1 on flow and 1 on return), auto bypass valve, 3 bar safety valve piped to outside and to minimum 100mm from ground, 2 x 3amp fused switches with neons, heat resistant flex, permanent live to stat, pipework, fittings, etc. Heating system should be flushed and an suitable inhibitor must be added to the system. I would normally install a new circulating pump and 2 new gate type pump valves when fitting a new boiler.
Oh and labour cost also!
