Vented system to Combi

[TotalR]

Hi,

So I can get my head around the work involved in this. currently have vented system with boiler in kitchen. Moving to Combi, staying in kitchen. has 22mm gas suuply and condense pipe can go straight out the wall. Hot & cold already in cupboard.

in the airing cupbaord what needs to be done to the Feed & Return here? system is as below but with 2 valves one for heating one for HW.

Why wow? Days work with £1050 boiler/flue.

Days work?

I hear the clicking of spurs.

I've just done a similar quote. It's for a customer that I have been working for for a couple of years so looking after him. I'm twice that price though and that's far from expensive. Fair play to them if they do a good job. In answer to your original question, is pretty much what you think of you've chosen to not repipe in order to keep the costs down. Depending on floor good they may even be able to link it under the floor. Have you thought about adding a very small radiator in your airing cupboard? It's nice to still have a bit of heat of you intend to still put stuff in there. Good luck, hope it goes better than the price is indicating it will!

Like every single engineer has pointed out already well too cheap. The 1500 is not near a quality job. If somebody asked for double than you are more likely to find somebody with skills, pride and not to forget knowledge. I’m quite sure you will not be happy with that boiler due to the pressure loss when having a 2 showers on in the same time. It seems like you cut more corners than the engineer and I was always under the impression people would like to get things done accordingly. You are far off from 1 days job, I never came across one conversion where it took me 1 day. A combi swap might be possible but a conversion is not possible. It doesn’t not matter how much an experienced engineer earns a day even if it was a 2k ... you are not paying just for the install, you pay for the whole package like knowledge, design of the system, tools, etc...

I do agree with op although I do agree with you professionals, so just to clarify
The job can be done in one day, I’ve done it several times myself, even easier with a boy. The only conversion I wouldn’t tackle in 1 day would be back boiler although I can get the conversion done and working I prefer 2nd day for removal of bb and tidying up, 3 days is a joke and I would question your ability.
£450 for a days work I’d do it no problem without cutting corners and fully registering it, you professionals seem to forget your working in a trade where the hourly rate is £15-£25 per hour, sub-contracting installs can pay £250-£350 with extras for power flushing, valve changing etc there’s plenty good engineers out there who would see this as easy money, then there’s a potential scrap value adding. Some engineers also have access to pipe, fittings and tools from there day to day job, now that doesn’t compromise quality but helps making price cheaper.
I’ve never seen any engineer telling people they will have to fully repipe the hot water as this can be impossible, all conversions can have problems unless fully re-piped
£1050 will buy a cheap cheap combi with those controls, be prepared for it not to last and warranty not held up

And in the above statement is everything that is wrong with this industry, that the skills, knowledge, risk & hard work can be valued so poorly.
Dake205 given the off site time to register, order & collect materials, along with overheads & GSafe you see this as value for your skill set?

so your saying steal from your employer and not all engys are gas safe off company time, also how are they registering them as it goes therough there employer, there going to look dim on there lads if they find out there doing that on the side

 

[Dake205]

The only thing I agree on is risk mate it’s plumbing and connecting on to old is always risk
Hard work is doing it in a day lol
Most boiler manufacturers now register the install with gas safe when you register warranty
Email/phone suppliers and it can be sorted ready for collection or delivered direct to site or in this instance customer has sorted that already
Overheads I’m sure that’s covered at £450 a day
Like I said most companies value your skill set actually lower than £15 an hour but if worth your salt the max is £25 until subcontracting

 

[Dake205]

Yes they are stealing from there employer and yes you can hold more than one gas safety, I had 3 at once

true but if there taking fittings and pipe from there enployer its unlikely theyve got there own gas safe reg

 

[Dake205]

Really they’ve got the materials, company van fuel cards scrap and earning £450 a day at weekends you think there going to not pay £172 renewal a year

 

[The Ancient One]

I would advise getting some serious advice before changing anything - your high Gas bills are probably more to do with how you use the system and how it is controlled etc etc.

 

[finchy01]

Stupid question. You have had the gas checked to make sure you haven't got a leak I assume.
