What is a Hybrid Heating System?
- A Hybrid Heating System consists of 2 (or more) heat sources that combine to provide space heating throughout the heating season;
- One heat source is typically gas based (NG or LP; examples: furnace, or a hydronic furnace with a combi-boiler, boiler, or tankless water heater, etc.);
- The other is typcially electricity based (air source heat pump, ground source heat pump, or a hydronic furnace with an electric boiler, heat pump water heater, electric water heater, etc.);
- Homeowners can manually choose which energy source you want to use at any particular time; or the switching can be automated using the iFLOW Smart Hybrid Heating Controller;
- With the iFLOW Smart Hybrid Heating Controller, homeowners select a set of criteria parameters that automatically switch between energy sources. Switching can be based on outdoor temperature, time of day (to avoid peak energy rates), to minimize operational cost or to optimize GHG reduction.
How to Create a Hybrid Heating System?
iFLOW has a suggestion to improve a heating system’s efficiency while lowering its overall operating cost:
- Replace an old air conditioner with a new iFLOW inverter driven, variable speed heat pump to create a smart hybrid heating system (electric HP & gas furnace); keep your existing furnace or upgrade to an iFLOW Hydronic Furnace; either way, you will need to change to a matched evaporator in Canada to claim C$5,000 grant on the iFLOW 2T, 2.5T and 3T models;
- Use the iFLOW cold climate heat pump during the shoulder seasons when the COPs are highest (Sept., Oct., Nov.; Mar., Apr., May), and when the gas furnace would typically be cycling, resulting in reduced efficiency;
- Switch to the gas furnace for the coldest months (Dec., Jan., Feb.) when heat pump efficiency drops (COP values drop), and when heat pump may not have the BTUH capacity, but conversely when a furnace would typically have longer running times, offering its top efficiency;
- Home heating capacity (ability to deliver BTUH into the home) is not at all compromised.
