Tankless Water Heater

Tankless water heater

In late 2004, Enbridge Gas Distribution Inc, Union Gas Ltd and Natural Resources Canada established a research project with the Integrated Energy Systems Laboratory (IES) and Canadian Centre for Housing Technologies (CCHT) to assess the relative energy performance of a tankless natural gas-fired system, as compared with conventional domestic hot water (DHW) installations. The tankless system was installed and commissioned in a single-detached Test House at CCHT.

In June and November of 2005, the tankless water heater was tested with imposed domestic hot water loads through simulated occupancy protocol. Its energy performance was compared to the energy performance of a reference water heating system, a storage-type power-vented water heater, installed in the Reference House at CCHT.
