    hello .

    Looking to buy a house but it seems all the rooms has some funky 70's looking gas heaters in them. So im guessing these use gas and the combustion process occurs in each room as opposed to a central boiler pushing hot wet around. The gas pipes feeding these seem to be standard radiator pipe thickness. <y question is If I upgrade to combi boiler and radiators, can the existing pipework be used for feeding the radiators?

    And just in case i need to start from scratch, its a classic two storey 3-4 bed semi . I only had a quick viewing but estimating I will need about 13 radiators a cobi and depending on th eabove, new pipework all round. How much should this set me back to the nearest £500 in Canterburry area?

    many thanks for your time.

    Well the simple response to your first question is that you'll need completely new pipework fitted. The existing cannot be used, and so will need to be ripped out.

    We don`t even know which boiler you think you want (note think) so it is impossible to answer chipwright, get people in to quote for a full installation.

    Back in the day, we used to say a price for the boiler and then per rad,

    now a guide maybe 2k for good boiler , and say £300 per rad, as a guide ?

    good luck

    Above estimates seem reasonable. Laying copper pipework is a labour of love, can save yourself a fortune by DIYing this, but boiler needs a gas safe trade.
