Immersion Heater - best one to buy ?

[macabethiel]

Our Immersion heater that was replaced just 3 years ago when we had our heating upgraded has failed it is tripping the RCB. Can heat the water via the boiler but always liked the backup of an immersion.

We are not in a particularly hard water area our last immersion heater element lasted about 25 years.

Anyone got a type or make they can recommend- local builders merchants ones are priced at around £15-20 it is a short one 11" or similar top fitting.

I have a pucka spanner so will drain down and do myself. Local firm wanted £200 to supply & fit a new one! I guess he did not want the work.

You need an "incoloy" heater (spelling probably bad but near enough) if it is going in a standard 36 x 18 cylinder then you need a 27 inch to heat most of the water unless you specifically only need to heat the top part which will be quicker due to the lesser water volume, Rick

Found this with 5 year warranty on heater part - expensive though.

Did not realise that you could pay this much for one £75 !

Guess you only need to heat the top part of cylinder, so yes first one is fine "incoloy" last you out, Rick

You would be just paying for a name, Rick

Hi, I couldn't view the links for some reason but I presume if your only buying an 11" one the element screws in the side at the bottom of cylinder. Anyhow, the advice I offer is don't put a steel/stainless steel heater in a copper cylinder and vice versa, I'm sure you'll know about the electrolytic table :thumb2
