Might be more worth upgraging the boiler in the long run if it’s an ancient one?
Yeah boiler’s fine, it’s just a long run to the bathroom – it runs along the ground floor, past the bathroom and up the wall, then has to go back on itself to get there. Not really an issue for the shower, just takes a while to get hot. But for the basin tap the boiler probably fires multiple times without the hot ever reaching the tap. We’re getting better and not running the hot, but it would be nice to be able to 🙂
OP: I have one in my office that feeds the kitchen sink and the bacon in the toilet.
I think it’s a Zip and has a 3 or 5L tank* with thermostat that it heats up so there’s no waiting.
Just plugs into a socket and I have it in a timer.
They are an easier solution electrically as, like you say, it could just be plugged in. But not ideal for our intermittent use, we’d constantly be heating water up that doesn’t get used.
