Compulsory central heating upgrade?

Hi,

My old Parkray has finally died so I'm looking at replacing it with a multifuel boiler stove. A HETAS installer came round today to quote and says we're legally required to fit TRVs to all radiators and replace the hot water cylinder (existing is old style with a jacket).

No argument that TRVs are a good idea, less convinced about the cylinder as I could just buy more jackets....plus the airing cupboard is in a bedroom with no radiator - if I improve the tank insulation I'll probably have to install a radiator.

I don't believe this is a legal requirement. I know that if I choose to replace a cylinder it must comply with modern regulations and I'll believe that if I wanted to extend the system I'd need to get into upgrading controls but I'm sure that a new boiler can be fitted in place of an old one without having to bring the whole system up to scratch.

We don't have access for tankers so it's a choice of sticking with solid fuel or using bottled gas at £46 per 47Kg. As the man is also a Gas installer I think he'd rather we just had a combi.

Interesting that one of the quotes I have for gas is for a heat only boiler connecting to the existing tank.....

Even solid fuel boilers don't quite last for ever so I'm hoping someone else has experience of replacing one?

    Building regs do require energy efficiency improvements when a boiler is replaced, including TRVs. The full requirements are here.

    Your biggest cost is going to be the fuel you use. There's a useful comparison here.

    Bottled gas is a very expensive way of heating a house.
  • Thanks Robwiz,

    I had actually found that document but was still unclear. It refers to a replacement system or component, then goes on to detail the requirements for the system. I think I'm interpreting it as applying only to the component being replaced but he's interpreting it as the whole system. The doc doesn't actually specify that it only applies to a new component but if he's right then simply replacing one faulty valve could require a whole new system? If he won't accept that I could just walk away but it becomes a point of principle!

    Bottled gas works out at 7.1p per Kwh, coal is 3.6p. I just manage to get enough free wood to run the burner in the living room but would have to buy it to run CH, probably at a similar cost to coal.

    My wife would like the convenience and cleanliness of gas but I'm not so keen to pay 100% premium for it!

    Check out the vat situation re upgrading your system. AFAIK you can get the controls & any work associated with them done at 5% but replacing a boiler or tank is 20% but if the controls are replaced at the same time as a boiler then it's all 20%.
    So it might be worthwhile having the job done in two stages (or invoiced at two separate jobs)


    I think most of the "engineers" who go on Gas Safe & Hetas courses are trained to upsell as much as they can by quoting the regs and hoping that you haven't already read them.

    The installer needs to be very careful issuing 2 invoices because a VAT inspection will be all over it and make him pay the 'missing' 15%. There is a legal term for this but I can't remember what it is.

    I have a Parkray solid fuel central heating system with hot water cylinder upstairs and header tank in the loft. I'm very interested in having a heat only gas boiler attached to the system with minimal installation work doing. I already have a gas supply to my property.

    Can this be done or are the regulations all pushed towards ripping everything out and putting a combi in?

    Also with these heat only boilers attached to the current system, would this mean I can still pick and choose when to light the Parkray without switching the gas boiler on for the those cosy winter nights?

    There are several threads about combining a solid fuel fire/boiler with a gas CH system.


    You will need something like a Dunsley neutraliser(do a search for that term) otherwise you will run into safety issues.


    I had combined open fire/gas system(not with a Dunsley) but decommissioned it because it was more trouble than it was worth.
