Electric Tankless Water Heating - thoughts.....

becks92

storage heaters on E7 so only at night when we are asleep so no fear of using too much at once.

We know we have to have another ring main put in for the shower but will speak to a sparky before going ahead with anything.

Thanks guys for all of your help.

Does anyone know of any brands that are accessible in the UK? Was looking at Ecosmart which is a yankee brand and seems get good reviews.

Dont let whoever is putting your new system in take your copper boiler away, they are worth a fortune nowadays,

Someone said on the TV this morning that copper was £6k a ton, so retain it to sell yourself

Already got that sorted McKneff

You may be better off running your shower off the heater, essentially the electric shower is just a smaller version of the same

Many houses I see have 60A main fuse, and 12kW is over 50A. Personally I wouldn't connect up in this situation as you couldn't demonstrate that there was no potential for overloading.

Hope you don't have hard water because anything you put in will be dramatically effected. the beauty of a tank fed system is that you can keep water under 55 degrees C - above this is where the worst deposits form on heating elements etc. I would only recommend demand style electric heating units where you are in a soft water environment which you can create using an appropriate water softener which has its own cost implications!!

Would never have a tank again, all that bacteria multiplying!

And with regard to hard/soft water and instant water... how about gas combi boilers?

No you don't. You put in a dedicated radial circuit that feeds only the shower (along with a RCD device if not already fitted on the CU). And the circuit will need to be designed in order to deliver around 42A safely if you use that 9.8kW shower.

You need the new Stiebel Eltron, the 13.2kw. They have discontinued the 12kw model. I bought one for around £220 from here http://www.directtradesupplies.co.uk/stiebel-eltron-dhf12c1-13-2kw-instantaneous-water-heater.html

This is the best price I could find on the net and I searched everywhere I could think of and then some !

Depending on installation you'll need 10mm or 16mm cable with a 50A breaker. I know 13200/230 = 57A but you ain't going to be using 13.2kw straight off and forever.

There is not other cost effective solution and I've been using these and their Panasonic equivalents (not available in the UK) for over a decade.

12kW is a BIG load to add onto a normal domestic property, esp if you already have storage heaters. You may need to have your incoming electricity supply upgraded, which will be extremely expensive. Best to get an electrician in to give some advice

My incoming was 60A and a quick telephone call to the electric company had a man coming round a few weeks later to upgrade to 100A for the cost of a cup of tea !
