Domestic Hot Water

Hot water is an essential part of residences and many commercial and industrial premises. Valutech has been supplying heat exchangers for hot water systems for over 20 years.

Domestic hot water solutions provide an economical, dependably and sanitary supply of water. Tap water can systems can be instantaneous providing “endless” access to hot water, or semi-instantaneous which provide domestic hot water and hot water storage.

Indirect domestic water heating (DHW) has seen a rise in use over the years due in part to residential systems having adopted Hydronic Heating from boilers and renewable energy sources. In North America, indirect domestic hot water heating is often implemented in condominiums and apartment complexes, as well as more commercial and institutional premises.
