Hot water systems in Waterloo
In Waterloo, more locals are rethinking their old gas and electric hot water system and upgrading to efficient options like a heat pump hot water system, solar hot water system or modern electric hot water system. With a young population (median age around 32) and lots of professionals in apartments and townhouses, residents want lower running costs and reliable hot water without wasting energy.
Waterloo’s dense housing – more than 12,900 flats and apartments out of roughly 16,500 dwellings – means hot water needs to work hard while using as little space and power as possible. Average household size is only 1.9 people, so a compact but energy efficient hot water system is often ideal. Swapping out older gas or resistive electric units for a modern heat pump hot water system or solar hot water heating system can deliver substantial annual hot water energy savings, especially with rising energy prices. The local solar exposure helps too: Waterloo averages about 16.5 MJ/m² of sun a day over the year, which is roughly 4.6 kWh/m²/day – plenty to drive both heat pump and solar hot water performance.
Across 2017 Waterloo, efficient hot water is starting from a small base but growing. There have been 22 efficient hot water installations (heat pump and solar hot water) recorded over the years, with busier periods in the mid‑2000s. While numbers each year are modest, they reflect a steady interest in electrification, lower bills and moving away from gas hot water. As more apartments are refurbished and older systems reach the end of their life, demand for heat pump hot water installation and solar hot water installation is expected to rise.
For a typical Waterloo household, hot water can easily be 20–30% of total energy use, so the right system size and technology matters. Brands like Rheem heat pump hot water and Sanden heat pump units are popular for ultra‑efficient heat pump options, while Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are well‑known choices when roof space allows. If you are comparing heat pump vs solar hot water, many apartment residents lean toward compact heat pumps, while terrace homes with good roof access can make the most of a solar hot water tank replacement.
Average bill savings will vary, but these ranges are common for Waterloo homes:
• Old electric hot water to heat pump hot water system: $350–$700 a year • Gas hot water to heat pump hot water system: $250–$600 a year • Gas hot water to solar hot water system: $200–$550 a year • Old electric to efficient electric hot water installation backed by rooftop solar: $250–$500 a year
When you are weighing solar hot water vs electric hot water, or electric hot water vs gas hot water, it is worth looking at both running costs and the hot water system price / cost over the life of the unit. A quality heat pump hot water price / cost or solar hot water price / cost can look higher upfront, but the most efficient hot water system choices often pay for themselves in just a few years through lower energy bills.
Hot Water Rebates, Tariffs & Savings
Waterloo homeowners and investors are increasingly using rebates to make an energy efficient hot water system more affordable.
