In the UK your dishwasher is typically connected only to the cold water intake, so that’s not a problem unless you have multiple showers in your house… that said, water heaters are often limited to either heating or hot water (not both at the same time), but that’s not an issue in practice since you’re not going to be using the hot water for long periods of time.

Nollij@sopuli.xyz 10 months agoI’m intrigued- does that mean the UK uses “tankless” water heaters, at least in smaller residences? Are they underspecced that they can’t handle a shower at the same time as a (typically) 3.5 gallon dishwasher?

Speaking for The Netherlands here, but I believe our situation is very similar to the UK in this regard. A lot of houses are equipped with a gas-powered tankless heater which supplies both central heating and hot water. These come in various sizes and output capacities, so you can install one which comfortably suits your needs. Using hot water for multiple things at once shouldn’t be an issue if you have the right heater installed.

Same in the U.K. Although my experience is that you’ll have to have a gas boiler with some buffer (40L say) to not experience a pressure drop of hot water when somebody else washes their hands. It doesn’t matter how often I’ve heard a plumber say “you won’t feel the pressure drop with this bad boy installed”; you always feel it.
