Instant tankless electric water heater?

[DuckyUC]

Great contacted coop energy today and they able to do a upgrade of electric service to 100Amp, so now the question is what is the highest kw/amp water heater I could use?

Model	Recommended Breaker	Maximum Amperage @240V	Recommended Household Electric Service	Recommended Minimum Wire Gauge
ECO 27	3 x 40 Amps DP	112.5 Amps	200 Amps	3 x #8 AWG
ECO 24	3 x 40 Amps DP	100.0 Amps	200 Amps	3 x #8 AWG
ECO 21	3 x 40 Amps DP	87.5 Amps	200 Amps	3 x #8 AWG
ECO 18	2 x 40 Amps DP	75.0 Amps	150 Amps	2 x #8 AWG
ECO 11	1 x 60 Amps DP	57.0 Amps	125 Amps	1 x #6 AWG
ECO 8	1 x 40 Amps DP	33.0 Amps	100 Amps	1 x #8 AWG
POU 6	1 x 30 Amps	29.0 Amps	100 Amps	1 x #10 AWG
POU 3.5	1 x 30 Amps	29.0 Amps	100 Amps	1 x #10 AWG

I know the ECO 8 is the open it recommend, but is it possible to fit ECO 21/18/11? as there will be a "save margin" for the Max amp use. I prefer the ECO 18 so even at the peak there still 25Amp left

You need to consult an electrician before making any decisions.

True, I keep google electrician and plumber around birmingham now, any good way to find them?

Post a thread in the 'I'm looking for a plumber / gas engineer' section of these forums remembering to include your location. [DLMURL="http://www.ukplumbersforums.co.uk/im-looking-plumber-gas-engineer/"]I'm looking for a Plumber or Gas Engineer[/DLMURL]

Ask for someone with Part P.

Thanks!

What is part P.? a safety cert?

 

[Dotty]

Part P building regulations. Refers to testing of electrical installations.

I would also advise contacting our electrical brethren on the UKEF - [DLMURL="http://www.electriciansforums.co.uk/electricians-unite-jobs-your-area/"]Electricians Unite - Jobs In Your Area - Electricians Forums[/DLMURL]
