How to Buy Electric Showers or Tankless Water Heaters

In England thay are called they call them electric showers whereas in the US they are more commonly known as tankless water heaters. If you’re thinking of buying one, the first thing you want to do is not to  expect that it’s going to give you a great high-pressure shower. With a regular tankless water heater, you’re going to get your hot water at the kind of pressure your building is able to supply it.

If you’re looking for an invigorating high-pressure shower, you’re basically looking for a pumped power shower. Right now though, we are just going to talk about a regular tankless water heater that consumes so much power – up to 10,000 W of the stuff –that it can heat water as quickly as it passes through the heater.

You know, 10,000 W is quite a number. You could run eight full-sized 12,000 BTU air-conditioners off that kind of power. But that’s rather okay for a shower. Because how long are you going to be in there – 20 min. at the most? If your power costs you 35 cents a kilowatt hour, you’ll just be spending 10 cents for the full shower.

Now you might be tempted to look at storage water heaters, because they usually consume perhaps a fifth this kind of power. The thing of course is that tank heaters heat more water than you can use. That’s electricity wasted right there. And anyway, when you have a tank, the water constantly gets cooler and cooler as you use it. And that can be very annoying.

The great thing about electric showers or tankless showers is that they need only a little bit of plumbing work – mostly DIY stuff. Of course, since it’s going to take all that power to heat your water, you’ll probably need to call an electrician in to install an independent fused electrical supply circuit.

Okay, before you buy, you probably have a few questions about what your experience will be like. Most electric showers or tankless heaters will put out about a gallon of heated water out every minute if you’re trying to take a shower in the middle of winter. Now this is hardly enough. A real invigorating shower requires at least three times that much. How do you make do with so little?

That’s what they sell water-conserving showerheads for. These put water out in a way that will make you feel it’s more than it really is.

There is another problem with buying tankless heaters – these aren’t exactly long-lasting or reliable solutions. Since those heating elements have to heat up so much, they generally build up limescale deposits rather quickly. You should probably choose a model that offers you a three-year guarantee.
