Heat Pump Efficiency/Moving Pump Question
Comments (12)Thanks for the input. The builders were cheap. There were a number of problems we discovered after moving in. Most of it is detail stuff, but they cut corners where ever they could. It's a 4 story building. We own the bottom two floors, and our neighbors own the top 2. We have insulation in most of the exposed walls, but that's it. There's no insulation separating our unit from the neighbors, and I'm not sure there is insulation on top of the building the way a usual home would have in the attack because of the roof top deck. Not only this year, but the past two years their power bills in the winter are SEVERAL hundred dollars per month. Ours aren't quite that bad, but that's because we keep it as cold as an ice box and they're still higher than anything my friends in the area pay for similar square footage. Also, we can hear everything in the building. It's like the neighbors are in the next room. I've lived in multi-unit buildings before, but this one is the least sound proof of them all. I can only assume it's because there is no insulation in the interior walls and our ceiling. I don't know what else it could be? I'm admittedly fairly ignorant on building matters, but these power bills are far from normal, and it's senseless that we have to freeze in order not to pay $500+/mo for power in the winter. I don't know what else it could be if not the heat pump/insulation. Thanks....See MoreBroken Heat Pump Liquid Return Line, Repair or Replace Heat Pump
Comments (2)I would (at least) go with flushing the lines out, adding a 2 way liquid drier and a suction drier. pull a micron vacume to 400, lock the system in the A/C mode and run it a week, then replace the liquid drier and remove the suction drier. Was the cut in the aluminum coil? A repair kit for that will be permanent. I don't know what you mean by damage to the "condensor"- that is the outdoor coil section. It is possible the system ran while it was raining (heat mode) and if a lot of moisture is suspected, checking the oil in the compressor would help make the desicion on which course to take. Many american standards have a 10 year warranty on the compressor and coil, so doing the above first would be my choice. If the unit needs replacing because of moisture contamination and it's that bad, the best route may be to replace the whole system for the long haul. Green oil and clumpy oil in the compressor or lines will indicate this extreme moisture contamination and installing filters driers won't work....See Morerheem heat pump system - message on thermostat - check heat pump

Comments (9)Sizing a Heat Pump Pool Heater. https://www.heating-air-conditioning.org/ You should have a trained pool professional perform a proper sizing analysis for your specific swimming pool to determine pool heater size. Sizing a heat pump pool heater involves many factors. Basically, a heater is sized according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as wind exposure, humidity levels, and cool night temperatures. Therefore, pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater. Heat pump pool heaters are rated by Btu output and horsepower (hp). Standard sizes include 3.5 hp/75,000 Btu, 5 hp/100,000 Btu, and 6 hp/125,000 Btu. To calculate an approximate heater size for an outdoor swimming pool, follow these steps: Determine your desired swimming pool temperature. Determine the average temperature for the coldest month of pool use. Subtract the average temperature for the coldest month from the desired pool temperature. This will give you the temperature rise needed. Calculate the pool surface area in square feet. Use the following formula to determine the Btu/hour output requirement of the heater: Pool Area x Temperature Rise x 12 This formula is based on 1º to 1-1/4ºF temperature rise per hour and a 3-1/2 mile per hour average wind at the pool surface. For a 1-1/2ºF rise multiply by 1.5. For a 2ºF rise multiply by 2.0....See Moremike_home
