Not enough hot water for two bathrooms to be run effectively

But These are the first people that come on here complaining that they don’t have adequate hot water or they think the installers done something wrong when they probably haven’t

Before buying, customers are attracted by combis because of the relatively low cost and extra space freed up by not having a HW tank.

After buying, customers are dismayed that what they also got was an inadequate supply of hot water.

The trouble with 'experience' is you don't get it until after the first time you need it.

 

[Riley]

I don’t know if it’s just me though, I think of myself as a very good communicator with customers and it is amazing the amount of them that are so misinformed when it comes to combis. They all think of a hot water cylinder, be it unvented or vented as being antiquated and think that a Combi is supermodern. I hear all the time people saying but that’s fine no one in our house showers at the same time but they can’t see how circumstances can change in the future or when they come to sell the property all these sorts of things will be flagged up and it will cost them long term

Another selling-point for me is what happens when there is a power-cut for more than a couple of hours. Life is a whole lot nicer if you have a nice cylinder of hot water...

Vaillant 938 combi storage best solution unless not many ppl live there and no one will take a shower in the same time

But that’s not future proofing Ron if it’s a two bathroom place it should have a suitable hot water set up. You don’t want a boiler to just about cope nor should it be the next house buyers job to spec it properly

Up to 3 Bathrooms Riley. No problem with this type of boiler. This type of boiler is a combi ... its Kind of combination storage designed for big family houses.

 

[Riley]

I know what it is but a Cylinder is still better mate. Can do up to 50 lpm whereas 938 can do up to 20. To me that’s just about coping with demand

Ron loves the combi’s Riley.

The op only has 16lpm tho.

 

[Riley]

Yes I saw that but it’s kind of reinforcing the point the combi isn’t really suitable

Yes! Why going back in tiles when you can go forward? Uk love to be 50 years behind other countries? However, you can fit even a stream Heating system if you wanted to, me personalny i am going with the future which in turn safes a lot MORE monety and hassle.

Riley, i understood what you meant. I just think that vaillant producent something which is made for purpose.

Unfortunately this country doesn’t do this product which would be also ideal

 

[Riley]

Yes and I’m all for things like this if it’s suitable for where you’re installing But it’s not fit for this purpose mate. The Op only has 16lpm that’s not enough for two bathrooms and I still argue that 20lpm is not enough to adequately run two bathrooms. I like modern and futuristic ideas, trust me I do but the spec quoted by Vaillant is simply not enough for me to take a punt and hope the customer is happy
