Why Should I Consider a Heat Pump to Heat My Boat?
Heat pumps are extremely efficient solutions for heating homes and buildings. But, do heat pumps work well for marine applications? It turns out that air conditioners with heat pumps are even MORE efficient on boats than they are in homes and buildings. They are very similar in operation to geothermal heat pumps (aka ground source heat pumps).
What are heat pumps and how do they work?
Heat pumps are basically air conditioners that run in reverse. They use a refrigerant (like freon) to transfer heat from one area to another through an ongoing cycle of compression, movement and evaporation. Our how marine ac works page explains this in more detail.
Heat pumps are able to capture heat from outside and bring it inside. They do this by using the outdoor medium (air or water, in this case) to heat up the liquid that was super cooled in the evaporation process.
In marine applications, instead of pulling heat out of the outdoor air, marine heat pumps pull heat from the water.
Top 10 reasons to consider a heat pump for heating your boat:
- Heat pumps also can provide air conditioning as well. In fact, all marine heat pumps we've installed are also very efficient air conditioners
- Marine Air Conditioners with heat pumps usually provide humidity control in addition to temperature control - so your boat can be truly comfortable on colder days, not just warm
- Some marine heat pumps now offer variable speed compressors and fans - to make them even quieter, more efficient and longer lasting
- Marine heat pumps can provide efficient heat in water temperatures as low as 40 F (this continues to go lower as technology improves)
- You can run a DC marine heat pump from Lithium Ion batteries or other high performance batteries. We've installed systems than can heat or cool all night without any generator power
- Marine heat pumps are very safe. They are computer controlled and have many safeguards in place to ensure safe operation. They also don't suffer from the funny smells of some resistance heaters
- If your boat has an air conditioner today, it can usually be replaced with a more efficient unit that includes the ability to run as a heat pump
- Marine heat pump units don't burn any fuel and don't create any exhaust gases/smoke unlike propane, kerosene or diesel heaters. They are much more efficient than conventional heat exchangers
- Marine heat pumps can be configured to run on 115v or 230v to match the voltage of other appliances on your boat
- New marine heat pump ac units are cost effective and can typically be installed in a day or so by professionals
