Renewing central heating system

[Bvrb89]

Hi, new to the forum.

im looking at buying a house in Lincolnshire, which needs a new boiler. The whole system is old and the radiators are not in the right places. I.e on inside walls not under the Windows. Before I put an offer in on the house I could do with a rough idea of how much it will cost me to do properly. It needs a new oil fired combi boiler and oil tank, 9 new radiators and new piping which is like as hidden as possible. There would be nothing in the house and it needs new carpets etc so I'm not worried about them being pulled up to get to the floorboards. It has a hot water cylinder in it which I would want to get rid off too.

and if anyone knows, what would the rough cost be of an air source heat pump system instead of oil.

thanks, Ben.

Think of an unvented hot cylinder together with an oil boiler. Combi oil boilers are trouble, expensive and will not have the flow rates the unvented unit provides if you have good mains supply.

Before opting for combi. ensure that water pressure and flow is adequate. Air sourced heat pump will require under floor heating and good thermal insulation of the building to keep running costs competitive. A ball park figure for combi, oil tank and rads would be 5K-8K depending on complexity. Builders place rads under windows to leave options for furniture arrangement. More thermally efficient is rads on internal wall, allowing ceiling to floor heavy drapes on windows.

Thanks for the replies. The reasons I was thinking combi boiler was because I have had a boiler with a hwc in a house before and found that I used a lot of oil, where as where I am now it is a combi boiler and I don't find it using as much oil. The house I am now in is much older than the previous propert and was built in 1870 ish.

As as for the house I'm thinking about buying, the heating system is from possibly the 60's and I don't know how longtime boiler t hasn't been working for. Do you think it is advisable to completely redo or should I just think about a new boiler and oil tank?

Rough price your looking at anywhere from 9-11k ball park for either system

And redo as no ones living there atm don't want to be changing things/opening floor boards when your in
