Heating Control upgrade Cost compaired to using standard boiler

jasgrif11

Hi,

What would I be expected to pay to get a new Oil condensing boiler supplied and fitted along with the sei grant rebate (High Efficiency Gas or Oil fired Boiler with Heating Controls Upgrade €700) compared to installing a standard oil burner?

Many Thanks
J

Difficult to know as depending on ur existing system adding in the controls may be tricky enough

Well the house is an old house but I removed the full system heating system from the house as it was ancient and in bad need of replacement. I will therefore be installing all new piping and 17 Radiators. I therefore just wanted to inquire is the high efficency oil boiler an awful lot more over the standard boiler when you take into account the extra €700 that you can spend with the grant?

Wouldn't imagine its terribly more expensive than a conventional boiler, but do be aware that a condensing boiler needs bigger rads to get the same heat out as a conventional boiler - I think the condensing boiler pumps more water, albeit at a lower temperature - and this is how it is more efficient.

If you're repiping - it would a good time to look at your controls / zones etc. You can save quite a bit of energy if you have say downstairs & upstairs zones (thermostat controlled) with hot water cylinder solo...

No, a condensing boiler will generate the same heat output as a standard efficiency boiler. it just won't condense all the time, if you want the boiler to condense more often then you would be absolutely correct with the larger rad sizes to achieve a similar room temperature, the aim would to be to get the water temperature below 55c to absorb the heat normally expelled by the flue.

To answer the OP's question i would go for the most efficient boiler and try and find one with a outdoor sensor/ weather compensator, look at the rating at http://www.sedbuk.com/ take off about 4 or 5 % of the rating of a condensing boiler as they only condense on start up in standard system, agreeing with Dardania i would have a least two zones IE.. bedrooms, bathrooms & sitting rooms, kitchen, i would add a inhibitor to the system water and defend it with my life, Gary.

One thing that seems not to have been mentioned in this thread is that by law you now MUST install a condensing boiler. It's in Part L of the building regs.

There are some ifs and buts to cover very rare circumstances (e.g. not feasible to install condensate drain when replacing an older boiler, etc) but these do not often apply.
