If you have a Heat pump, you must set the thermostat up for "heat pump". Then you must connect all the wires up according to the manual.

If you do not have a heat pump, the wiring may be crossed or touching somewhere.

Call a local heating and air conditioning company to trace out the problem.

What would the water temperature be in a central heating unit if it was a model for electricity?

I'm not sure of your question.In the USA, most hot water heaters and furnaces are independent units. They can be either gas (methane) or electric powered. The hot water heaters are thermostatically controlled, and thus the water temperatures in the gas and electric water heaters would be essentially the same. The speed at heating the water depends on the HW heater design, but both gas and electric HW heaters would be similar in speed.I've heard of combined Hot water heaters and furnaces in use in Russia, with the side effect of only having hot water in the winter.Here in the USA, electric furnaces come in 2 varieties. Heat Pumps function somewhat like an air conditioning unit, and deal with heat differentials. In mild temperatures, they are more efficient than direct electric heating. However, the temperature increase is relatively moderate. It is likely they could only heat water to a "luke-warm" temperature.Using conventional electric heating, the electric heating elements can become extremely hot. Think of your stove with temperatures in excess of 400 degrees F. However, the actual temperature of water would be dependent on the design.I would encourage consulting the manufacturer of the device you are interested in with any device specific questions.


When heating liquid in a test tube what safety precautions are needed?

Before heating it, you should check the test tube for damage (scratches or cracks), and not use one that isn't perfect. You should also wear safety glasses (to protect your eyes in case the test tube explodes, which happens sometimes, even when heating water). If you are heating something that could react violently, you should use a blast shield (thick piece of clear plastic).


Why do room air conditioners ice up easier that central air conditioning system?

Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling . The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle. Another reason could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed. A central ac unit is usually out of sight externally to the dwelling or mounted on the roof.
