Saving money: 3ph house.. 3ph Cooker / Immersion?

[Dom.]

A friend of mine is moving into a house with a three phase supply. Now..

Picture this:

It's summer and it's daytime. There's nothing on but the radio. Lunch rolls round and the homeowner whacks the cooker on.

Is the excessive Neutral current/wasted electricity something to worry about?

Ditto with a 6KW Heatrae Saida. This will be used in the summer, when the wood-fire is not used.

He intends to retire to this house and he is basing all costs (roof, heating, kitchen, bathroom, windows, etc) on a life of thirty years.

Speaking pragmatically please, would your natural reaction, after a life-time of Sparking, be to:

a)buy 3p appliances where-ever possible to keep the load imbalances to a minium?

b)Make the effort to change the house over to 1ph?

c) say meh/pfff and enjoy your retirement?

Thanks

Dom.

Why do you think it's going to be cheaper to run 3 phase equipment over single phase?? All you'll be doing, is spreading the load over 3 phases!! You'll still have to pay for the total current used, be it spread over 3 phases or on a single phase!! What's more, 3 phase equipment will be generally more expensive (if even available) to purchase. DNO standing charges will also be more on a 3 phase supply, than that of a single phase supply.
