HEM hot water systems Hot water on demand

Calculating the hot water demand of a system can be a
tricky affair. Compensate too much and you have a large
inefficient system taking up valuable space and power.
Calculate too little and you run out of hot water when you
need it most. We can accurately calculate your hot water demand and design a system to suit whether it is new build or retrofit

Custom solutions

These custom made solutions are designed to suit even the most challenging retrofit installations. Each component is carefully selected as having the highest quality materials whilst providing the flexibility to be carried by hand to the desired location through narrow access ways, standard doors and hatches. The skid is designed to be able to be easily assembled and to suit existing foundations.

Skid mounted solutions

Our skid mounted solutions are ideal for new build yachts offering a plug-and-play design to simplify installation. The skids can be easily lifted into position during the new build stage, whilst providing good access for servicing in the future. The designs feature efficient tank-in-tank cylinders.

CS2 Heat recovery unit and controller

We have developed a new smart controller and heat recovery unit to complement our established hot water range. The small controller and valve assembly can be easily installed on new units or retrofitted to existing systems. The smart controller continuously measures the demand of the hot water and the available heat
from the heat source. When a demand is sensed, the primary heat source is monitored to make the maximum use of the heat before engaging the modulating electric boilers. If the primary heat source is not usable at that time, then the secondary electric boilers
are seamlessly engaged to ensure the hot water demand is met at all times.
