dead eye alan Posted August 16, 2017 Report Share Posted August 16, 2017 My boilers given up the ghost at last, so a couple of questions for the PW massive. 1/ how do i know how big a boiler i need. (24/28/33/40) 2/ how can you fit a combi boiler on an inside wall. 3/ how much should i be paying for supply and fit. ( my existing boiler is old style with storage tank ) 4/ is there a Watch member that can do this for me. Many thanks in anticipation.

fortune Posted August 16, 2017 Report Share Posted August 16, 2017 Give more detail about the system that you have now. Who has decided that it isn't a small repair. It's a big shell out for a new boiler and then to find out that a fuse had blown or similar. Quote Link to comment Share on other sites More sharing options...
JohnfromUK Posted August 16, 2017 Report Share Posted August 16, 2017 If we go with your boiler being beyond economic repair, there are various ways to look at what size is needed for replacement; Firstly - was the previous boiler undersized (i.e struggled to get radiators all hot in cold weather), or oversized (cycled a lot and never seemed to work hard), or 'probably about right'? Secondly - you can measure the sizes of the radiators and look up how many KW each can require - add up the total Thirdly you can look at the house as a whole (there are free on line tools to do this) and calculate the approximate KW needs Fourthly you can look at each room individually and calculate needs on a 'rooom by room' basis; this is usually done when having a new system, not just a boiler. Combis (or any boiler) can be had that have vertical flues through either an existing chimney or up through the roof, but any installer would need to take a good look as there are rules on location of flue exits etc and their proximity to windows, vents etc. Once you have the boiler size determined, you can look up prices on line, but installation costs will depend on how much work is needed to install it.

It's a big shell out for a new boiler and then to find out that a fuse had blown or similar. Funny you should say that. While working offshore our huge 250 ton lift Manitowoc crane stopped working .... would not slew left or right .. jib up or down. Now on board we had this six month trained engineer who convinced the bosses that the gearbox had to come out for repair. I asked if they had taken an oil sample to check for contamination or debris. They informed me that this would not be necessary as Malcom had already told them what had to be done. Now all you heavy lift crane operators out there will know what this work entails, and so the work began. I Myself walked around to the control cab and switched on ...... Nothing ... walked back to where they had just started dismantling, and opened up the fuse box. Guess what I replaced a blown fuse and it was all systems go again. Now just think of the Man hours ...down time ... possible loss of the weather window and all because some people never look for the simple things first.

Honey Monster Posted August 16, 2017 Report Share Posted August 16, 2017 Flushing the heating system before installing new boiler is a must. Manufactuter requirement. Get the magnetic filter isntalled together with a new boiler. Sizing? depends how old property is ( insulation) and is it one or two floor. Roughly you need 100 watts per square meter downstairs and 80 watts per square meter upstairs. would be good to check the radiators as well- seems you have old vented system so no inhibitor in rads and pipework= black sludge . If radiators are older than 15-20 yrs better to replace them. So typical combi 24kw is enough for most small and medium houses. Hot water demand is other thing. 24-28kw can provide 10-12 liters per minute. If you need more then worcester- bosch. Many models up to 17-20 L per minute. Price depends on many things. Amount of local gas engineers, greediness, how difficult job is etc. This is a lot of work- installing new boiler, new pipes for hot and cold to the boiler, new waste pipe for condensate ( pump might be necessary), removal of old existing tanks in the loft, hot wter cylinder, old pump and motorised valves. Decent boilers price starts at around 800 pounds till 1700. Labour I would say 1200-1500, so 2-3 grand in total . If new rads needed - plus 450-600 for rads and 200-300 labour. (if we are talking about 6-8 rads). Quote Link to comment Share on other sites More sharing options...

Seriously though if you could PM me the companies details i'm not a million miles away (assuming your dad lives in the NE too) and will need my boiler and heating system changed in the next couple of years Quote Link to comment Share on other sites More sharing options...
Tim Kelly Posted August 16, 2017 Report Share Posted August 16, 2017 It depends on the suitability of the boiler location. There are some pretty tight restrictions on where and how flues can be run. You will almost certainly need a new gas supply from the meter, powerflush, new room stat, thermostatic rad valves fitted etc to bring the installation up to current building regs. You're in the south east, so don't imagine you're going to be paying anywhere near the £1700 quoted above, that barely buys the parts! I would imagine you'll be north of £4k, how far north depends on the boiler position and the flueing. Quote Link to comment Share on other sites More sharing options...
kingnewport Posted August 16, 2017 Report Share Posted August 16, 2017 Around 2k. Depends on boiler location , if not on an external wall could push price up. Quote Link to comment Share on other sites More sharing options...

They all hung their heads. The bosses went for a cup of tea. The so called mechanic Malcom put his tools away and the incident was never spoken about again. Bonus I had more chance of catching Anthrax. Quote Link to comment Share on other sites More sharing options...
Del T Posted August 16, 2017 Report Share Posted August 16, 2017 (edited) That W-bosch for 1700 was like for like swap I presume. Must have been one of the lower speccd ones.!!The wb cdi classic that I'm on with at the moment retails at trade 1300quid plus vat! Plus clock etc ! A basic combi to combi swap I do is usually £2000. That's a wb 29cdi classic and basic time clock. A system swap conventional boiler to combi is from £2500 upwards depending on things like gas pipework, condense pipework etc. The job needs to be seen as there are so many variables.
