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.

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...
