Not sure about the legality (or not) of the pre-existent hot water boiler. With so many building regs now, is anything legal? I suspect that I'm being too honest already. I can imagine only a tiny minority of people accepting the £7k estimated cost of destroying and rebuilding their house that...

In an English Court of Law, a complainant must prove that he's incurred a loss. If the complainant's case is that the defendent asked him to diagnose a fault on his heating system, but has no paperwork to substantiate this allegation then there will be no case to answer. I'd recommend...

Found a document which does say that TRVs, a room thermostat etc. are required. It's not in the Building Regs Part L as is often specified, that just says that a boiler must meet SEDBUK A & B ratings. However, these ratings are only achieved by the boiler, if the items above are included in the...

Just how much steam do these condensing boilers pump out? My existing flue faces out towards the street and is to the left of my front door, about 1.5m from the wall between me and the street. There is a drain the otherside of the bay window and the rain gutter also empties in to that drain. If...

Radiators aren't very expensive and you can do the work yourself. To replace:- With my open-vent system, I go in to the tank and tie up the ball in the heating system expansion tank, then go down to my bathroom, attach a hose from the heating system drain plug and lay the other end in the...

From what I can tell (and until I receive a weblink to the contrary), the Building Regulations and associated Approval Documents only deal with the replacement of an existing boiler with a condensing boiler. They don't mention anything about having to make improvements to the central heating...

Do you have a weblink? The law seems totally vague on most things. The Building Regulations Act just seems to specify general requirements (See exact wording at bottom of this post). Most of the details on how to comply with part L of Schedule I of the act are contained in Approved Documents...

My situation is:- 1. I've got no drains upstairs so the condensing boiler can't go upstairs 2. I've got my instant hot water boiler in the bathroom, and the rest of the bathroom is tiled, so it wouldn't be economical to put it there 3. The only space against an external wall in the kitchen...

thanks. There seems to be quite a room for maneouvre in the guidance provided by the ODPM to meet the building regs. If a CORGI engineer signs the assessment form indicating that it's uneconomic to put a new condensing boiler in the kitchen/bathroom and signs the building regs certificate, is...

The boiler is starting to leak, and seems to be at least 11 years old, although some think the underlying system is nearer to 30 years old.

Thanks. Does this mean that I can't put the new condensing boiler in the existing living room site?

I've found 1 model which looks suitable - Vaillant Ecomax Pro. There are 2 types - 18E (5-18.6Kw) & 28E (5-28Kw). Bearing in mind I live in a 3-bed Victorian with 7 radiators, which type is recommended?

Thanks Chris, Does this mean that Condensing boilers can work with open vent systems? Do you know which Worcester/Bosch or Vaillant models would work with such a system? Cheers, James

As some of you know, I have an old-fashioned Servowarm Supreme radiator back boiler whose flue is currently located at the front of my house to the left of the front door. The guy that came around yesterday seemed intent on putting the new boiler in the kitchen or bathroom, and I was curious...

"What reason for ripping out the old pipes? Unless they're the steel ones I certainly wouldn't." He's not the 1st to say this, but doing some research it seems that combi boilers operate at 3 times the pressure of the older boilers like mine. That said, most old houses seem to have ancient...

Guy's confirmed that he thinks I need a whole new central heating system. Says that he can do it for a fixed price of £5000. However, a few things bother me with this:- 1. He wants to remove the relatively new instant hot water boiler which is in the bathroom and replace it with a new combi...

I understand that I'll have to insist on very fine detail with the quote. Is there any means that a plumber can test a system to see if it can withstand a certain pressure or not? Obviously the difference between a new boiler and a new central heating system is great enough to be concerned...

Sounds like things are tilting towards a complete replacement. Would the quote of £5000 for a new system be reasonable, or is it likely to mount up from there? Is there any way of telling how old a radiator is or indeed how old the Servowarm Supreme is. It's got a GC number on it.

Hi there, The hot water system is run off a seperate boiler which is one of those instant heat jobbies. Are TRVs required by the building regs or is this just a desirable? In my case, that would add a few hours to the costs, as some of the radiators appear to be soldered directly in to...

If you're bothered with cowboy customers then get them to sign a form acknowledging the cost before starting the work. Genuine businesses offer quotes & invoices.
