Immersion heaters
We can supply matching 3kW incoloy immersion heaters manufactured to the Maxistore specification. They are of a low density design and are very quiet in operation. This is very important when overnight Economy Seven electricity is being used.
We can supply 6kW and 9kW industrial immersion heaters for customers who want a quicker reheat performance. They can be wired for either single or three phase operation.
We can supply immersion heaters boxed but not fitted to avoid the danger of transport damage.
