We are very pleased to introduce the FTH 4. This is the most compact and cost effective version of the flow through heater range. It will deliver 97 degC water, from cold, in sub 5 seconds. It can be supplied as a bare heater or with everything included: water fittings, NTC, thermal protection. As a compromise for cost the FTH 4 is good for max 20 bar operating pressure but not for making steam.
