Hot water supply- Is this idea feasible?

Postby Homefront » Mon Aug 25, 2008 5:14 pm

I'm restoring a 1930s semi, which has fully functional open fireplaces as well as a 25 year old gas central heating system. With gas prices on the rise I'd love to ditch the c.h. system. I already use my open fires successfully for heating and just use the gas boiler for hot water. Is it feasible (and more efficient) to use an individual electric 'on demand' hot water heater for my kitchen sink and another upstairs for the bath? I'm thinking of the type that can be tucked away out of sight rather than those that hang on the wall with a spout. Ultimately I'd like to ditch the gas boiler all together. Is this scheme feasible?

I'd value any opinions.

Simply Build It

As electric is more expensive than gas, I wouldn't have thought so.

How much would it cost to fill a bath everynight, from an electric instantaneous water heater ?

I'd stick with the gas, maybe install a combi boiler. There's no pilot ans you only heat the water you need. No storage tanks to heat.
