In the nicest way that just means he’s a Combi slinger and probably doesn’t have the skill set to give you the work you require. Anybody that won’t entertain any other sort of system I would steer clear of

I couldn't agree more, hence why i asked anyone from Coventry on here who would look to provide a quote?
 
Definitely gas registered, how much would you have expected it to cost to convert to combi? Labour and parts?

I hope no corners are cut!

I've priced a few bbu out combi in airing cupboard and they have been coming in at around £2600-3000 with a 30kw combi.

If they are charging you £600 labour and materials then my guess is it's a cash job and they will be stealing from their bosses.
 
I'm going to get a few more quotes to upgrade the current setup, having second thoughts whether fitting a combi is the right thing to do 🙁
 
Your initial proposal is probably tolerable should you stick with the electric shower. However it’s overkill size wise fitting a boiler like that when your heat requirement is probably less than half the boilers capability plus you will get a much more satisfying shower or showers should you go down that route from an unvented cylinder (supplies allowing)

Although the boiler is oversized from a heating perspective, would it not modulate down to adjust?

The vogue has Up to 7:1 modulation, what does this mean?
 
The boiler can be range rated accordingly. But let’s not kid ourselves you are getting it for the hot water supply correct? You don’t know that your incoming mains pressure and flow are adequate to supply the boiler with what it needs. The thing with that is if it is adequate then why would you want a drop-in flow every time someone opens up a second outlet which is exactly what will happen with a combi boiler. This is where these high kilowattage combi boilers are a difficult decision. You would get one pretty good shower to outlets open is never going to happen

Yep, definitely for the hot water supply, rather than the heating, in our previous house, we had a combi very rarely the bath/shower and kitchen taps would be used at the same time, this is the only time i recall a drop in water pressure. In light of our circumstances that's why i think a combi will also be suitable
 
I agree with the above mate. I don’t like the idea of a combi in a 4 bed.

Not so much a combi in a 4 bed as I believe there are times it's acceptable to install a combi in a house that size. I know I'm in the minority on thinking that as we've been down that conversation before a couple of times.

Reason I dont really like them is because people think they are suitable for running 2 bathrooms at the same time. If you have 2 bathrooms and want to use them at the same time then get an unvented if you dont want to use them both at the same time then get a 30-35kw boiler.
 
I agree with the sentiment you are talking in your current situation but I don’t understand why you don’t future proof in case your family grows or you take on a lodger that sort of thing?? The combi boiler will not be sufficient for using both bathrooms or likely even the hot tap in the kitchen and the shower

Its one bath and a separate electric shower in another room but definitely won't be used at the same time. Maybe on the odd rare occasion.

30-35kw vs going for the 40kw will there be any advantages?
 
I know I’m playing devil‘s advocate but what’s the point in buying a house with two bathrooms if you’re never going to use them both you might as well have bought somewhere smaller, I know that’s not the point in question but you seem to be trying to use every argument to justify a combi boiler when we are giving you the honest opinion that it’s not the best answer for your property. I realise your mate is giving you a good deal on it but don’t undersell your home for the sake of saving a few quid as you may find you’ll be ripping it all out and changing it in the future

I totally see your point, in the future we are planning on converting the loft so wouldn't want any tanks, i presume there are tanks in the loft? Is there a solution/setup where i just have the cylinder and boiler?
 
Seal your heating system - f&e tank goes
Install an unvented cylinder - cold water storage tank goes
 
Seal your heating system - f&e tank goes

Ah ok, can you explain further when you say seal the heating system, what's needed to do that?

So i can get rid of both tanks in the loft? And get an unvented cylinder?

Can you recommend an unvented cylinder and boiler?

Is there alot of alterations to the pipe work to do this? Any idea of costs?

What's the maintenance compared to a combi?
