    I want advice on a new boiler, to be installed into newly installed ‘conventional radiator’ and hot water system.
    We have no room for provision of a hot water storage tank, and no loft space. three floors (including attic) in an old detached stone built house. 5 beds 2 bathrooms 2 ensuites each with shower, w.c. and small handbasin.

    House has 15 radiators, three heated towel rails, kitchen sink, washing machine and dishwasher.
    It seems that the new L regs severely restrict the amount of hot water output available through condensing boilers, the highest I have seen here is 20 Litres per min.

    If need be, we could install an outside boiler cupboard and put a water storage tank within the existing airing cupboard, which we intended to take a wall mounted boiler, Note: the radiator system has been plumbed up using push-fit copper joints and copper pipes throughout (conex cuprofit) and (speedfit copper).
    Main spine of system in 22mm individual rads tee’d of in 15mm, TRVs throughout.

    Please reply by email initially giving suggested boiler spec and price for installation of the boiler to exisiting pipework,

    You could benefit from an unvented hot water system which uses a regular condensing boiler but the cylinder is fed from the mains so there are no header/feeder tanks needed. The unvented hot water cylinder can give feeds of upto 40 litres per minute and can feed multiple draw offs at any one time. This would appear to address the flow requirements you would need.

    Whilst we hope that this information has been helpful the installation at your property is not a standard installation and we would not wish to quote a price when so many other factors could change the installation cost. We want to give you a firm accurate quotation which takes into account the challenges at your property and your heating requirements. For this reason npower are able to send a Home Energy Consultant who can visit your home and, having established all the facts, provide you with a free, no-obligation quote.

    Please could you advise on a new boiler. I am soon to have some building work done on my home which will involve draining the central heating. This would seem to be a good time to replace my boiler which is about 15 to 20 years old. I have a stored hot water system with the cylinder in the loft along with the header tank. When the building work is finished I will have 12 to 13 radiators. I have 11 radiators at the moment and have been told my present Baxi WM 511 RS boiler is not really big enough and that it is very inefficient due to its age and type. I have no room thermostat but each radiator has a thermostatic control. The house is a 3 bed semi. and the present boiler is in a cupboard under the stairs and is wall hung half over a small barred window. The vent is facing next door with only 2 to 3 feet to the boundry wall. There is no other place I could put the boiler.

    What type of boiler do you think would be best and how much will it cost including fitting? Are there any building regulations involved? Please email reply. Thanks.

  • Boiler Systems says:

    The government changed the regulations in April 2005 stating that any new or replacement boiler has to be condensing, condensing boilers are more efficient (91% efficiency and better). The latest regulations also state that the flue has to be at least 600mm from any boundary line going upto 2.1m for certain boilers where the boundary line has openings into the opposing neighbours property. You now also have to fit a room thermostat under the same regulations.

    npower are able to send a Home Energy Consultant to your home to review the installation options, go through viable places inside your property where a condensing boiler could go, and help to select the right boiler for your home, there are several options. This visit is free with no-obligations on your part and will also enable an accurate quotation to be developed for a new boiler.

    can you tell me why 2 corgi registered plummers tell me i need between 1.5 & 8 bar water supply pressure but a salesman tells me i need a minimum of 7.5 bar water supply pressure. i’ve checked on manufactuers tech details which tell me the same as the 2 plummers. (wanting to replace my back boiler with a combi boiler but my supply water pressure is approx 5 bar)

    There could be many reasons why the several sources vary in their advice and it is impossible to say on the limited information in your note.

    If you have three advisors the best advice we can give you is not to seek a forth opinion from this site but to challenge the advisors with the conflicting information and ask each of them to justify their comments. Make sure that they explain, to your satisfaction, their reasons such that you feel confident of the purchase decision you will soon make.
