What warranties should I look for when purchasing a HWHP?

Warranties vary by manufacturer. Read the conditions carefully, especially those concerning labour. Some warranties require professional installation, regular servicing, and adequate water quality.

Recommended warranty lengths:
Heat Pump System: 6+ years
Tank: 5-10 years (stainless steel is often 15yrs)
Associated Valve Work: 12 months

Before buying, also ensure that prompt heat pump service is available in your area (it usually is, but it never hurts to check).
