Yes depending on electrical rates in your area , but you will need a backup system to provide heat when the outdoor temps get below 35* or so where a heat pump is ineffective. This is commonly called a Dual Fuel system. Many people do this.
A properly installed heat pump uses about one third of the electrical energy to produce the same amount of heat.
A reverse cycle A/C must mean a heat pump. Every heat pump has a C.O.P. or coefficient of performance. They are rated at 17 and 47 degrees outside. A new heat pump should be around 3.3 at 47 degrees and 2.1 at 17 degrees. This means even at 17 degrees outside, it will produce 2.1 btu per kilowatt to 1 btu per kilowatt of an electric strip heater. And 3.3 to 1 at 47 degrees. Depending on where you live though, the electric heater may be needed to supplement the capacity of the heat pump.
A Heat Pump while more expensive to buy than a gas heater has much lower operating costs. It is also much cheaper to install requiring only an electrical connection instead of a gas supply line.
More than likely you will not have heat being the water wont be circulating through the heater core , When the hot water passes through the heater coil the air passing through the heater coil makes heat blow out the vents when you have selected a heat setting on your controls.
No it doesn't, Night time heatloss is a big problem for pool heaters, as your pool pump runs it moves heat away from your pool, so you actually increase the night time heat loss by running your pool pump/heater at night. The most economical solution is using a Solar cover and leaving your pump off at night to prevent night time heatloss and then just fire up your heater when the temperatures begin to come back up to daytime levels.
It is cheaper to replace the heater core than it is repair it
Im really not sure of the question but if you are refering to using an electric immersion heater in a thermal store over a ground source heat pump, the immersion heater has a COP of 1 and the ground source heat pump has a COP of 3. So 3 times better.
You don't. If the heater has an electronic spark, then it doesn't have a standing pilot to light. The spark lights the pilot when there is a call for heat, which in turn lights the burners. If the heater is on and the pump is RUNNING, the heater should light automatically when the water temperature is lower than the heat setting.
There are many benefits to using a convection heater. The first advantage is the fact that convection heaters heat faster than other heaters. Convection heaters also are much cheaper and heat a larger area.
If you want to heat your pool you first have to turn on the pump because nothing works without the pump running. You will not get filtration, circulation or heat. Turn on the pump set the thermostat to desired temp range. If you are starting with a water temp of about 55 degrees more or less, you will want to run the pump non stop until you achieve a temp near your desired goal. -- Quicker recovery time with this method is achieved rather than running the pump a few hours then shutting it down until the next day etc. k
yes it does as the heat pump is more effeciant.
A pellet stove is a good room heater but may be much more expensive for overall house heating than a regular furnace.
