New Central Heating Boiler.

[Colortec]

What is the 'ballpark' price to supply and fit a new boiler.

Circumstances as follows:

Eight Radiators

Semi detached three bedroom home

Moderate to heavy use of hot water

Double glazed and loft insulated

Remember - we only need a new boiler - not the whole system.

Situated in Ayrshire, Scotland.

Any tips/advice much appreciated.

Down here in oxfordshire to supply and fit condensing
non- combi boiler would be about 2K which also includes a full system power flush to get the boiler through its benchmark test (boiler warrenty).

Colortec,
I'm afraid your comment " we only need a new boiler" may be an understatement.
Your Corgi registered installer has to comply with " part L" of the current building regulations.
This could involve the replacement of your radiator valves ( upgrading to thermostatic type ), replacement / upgrading of consumer controls ( programmer / roomstat ), and possible replacement of the domestic hot water cylinder.
I would advise that you collate 3 detailed estimates from well recommended installers.
From the information you have supplied, I would be looking below �2000 .
Hope this helps.

Thanks Pilotlight...... what an apt name you have.

Are you a heating engineer? If so I would greatly appreciate any input you can offer.

We are in the process of buying our house from the landlord. We will have some cash left from the mortgage and are looking at replacing the seventeen- year -old Worcester combi boiler.

We do not have a shower but instead have a bath, so we use a lot of hot water via the combi. I have been on the 'ideal' boilers site. However they don't give prices - just pictures and spec info. Do you know if it would be cheaper for us to source our own boiler - or have a supply and fit arrangement with an installer? Further, where is the cheapest place to buy half decent boilers.

As far as I am aware, the boiler should be operating at its maximum (not part load) for peak efficiency.

Property size is 6.5m x 6.5m with room height 2.4m.

Three bedroom with lounge, kitchen, bathroom, hallway and landing.

Colortec,
I would not recommend purchasing your own boiler, even though you would still have the benefit of the 2 or 3 years manufacturers guarantee, your installer might not be so keen to carry out an inspection should the boiler fail at anytime.
You should, first of all , check that your loft insulation complies with current standards ( 250 mm thickness ).Unless it has recently been installed, it will not comply.
Contact the Energy Effeciency department of your local authority to find out if you are entitled to any kind of grant regarding loft insulation and cavity wall insulation. If these are brought up to current standards, it could possibly affect the calculations required to size your new condensing boiler.
Regarding your comment re boilers operating at maximum
load, this used to be the concept when condensing boilers first arrived on the scene, but nowadays manufacturers design their boilers differently, with more technical components in order to achieve maximum efficiency.
You say the Worcester boiler you are presently using is 17 years old. This in itself tells you that Worcester manufactured boilers ( now Worcester Bosch ) can be relied upon, although not the cheapest by a long way. ( as with most things - you get what you pay for ).
Don't forget, 3 DETAILED estimates from CORGI registered installers who should provide any advice required.
Hope this helps.
