Tank or tankless: which fits your home?

Start with simultaneous use

List the showers and appliances you expect to use at the same time. A tankless unit must be selected for the required flow and temperature rise, while a storage unit needs capacity and recovery suited to the household.

Compare the full installation

A conversion can involve the fuel supply, electrical work, venting, and water connections. Ask for a complete scope so an equipment-only price does not hide the practical difference between options.

Plan for care and access

Leave room for servicing and discuss the manufacturer’s maintenance requirements. The system that suits your space and use is more useful than a generic promise of endless hot water.
