Gas powered heaters are a big part of what makes using one’s spa during chilly evenings enjoyable. That’s why it can be so disheartening when a spa heater breaks. The good news is that there are great replacement spa heaters available. You just have to know what to look for. With that said, here are our picks for some of the issues to consider before purchasing one:
Gas Type, Altitude Range and BTUs
If your original spa heater worked well, consider sticking with the same gas type, altitude range and BTU rating. If you weren’t happy with its performance, consider making adjustments. Adjustments should be made based on several factors, including the following:
- Availability and cost of an area’s utilities (i.e. propane, natural gas and electricity)
- Average outdoor air temperatures and wind strength
- Level of insulation used in the spa’s construction
- Spa heater’s thermal efficiency rating
- Size and altitude of the spa
Another factor to take into account is the spa heater’s ignition style. There are two main styles that you are apt to run across, each with their own advantages. The two types are millivolt and digital electronic. Millivolt ignitions tend to be ideal for use in areas where electrical service is spotty, inaccessible or expensive. That’s because they don’t need electricity to run. They use a pilot light instead. Digital electronic systems, on the other hand, obviously require electricity to operate. Thus, they are ideal for use in areas where gas service utilization is impractical or millivolt systems are prohibited.
Although the majority of hot tub heaters now run on electricity and use a heating element, instead of gas, make sure to follow our recommendations if you have a gas powered heater you need to replace. Or call us if you are considering switching to an electric heater so we can help you decide if that is compatible!
