Sep 19, 2011· Water source heat pump high head pressure Hey there, I was working on a water source heat pump Trane serial number# W04C11546 MN# GEVB02411J0110TL. The unit is an upflow with the compressor compartment being on the bottom and the fan and coil on top.
When the WATER FLOW light is on, this signals that internal freezing conditions have occurred. This may be caused by a pump failure, low antifreeze level or air pockets in the loop piping (see resetting the unit section, below). High Pressure When this light is on, it indicates high refrigerant pressure. This may be caused by a loss of water .
In regions without any high temperature geothermal resources, a ground-source heat pump (GSHP) can provide space heating and space cooling. Like a refrigerator or air conditioner, these systems use a heat pump to force the transfer of heat from the ground to the building.
Check that both the cables for the operating pressure switch are in position If the pressure switch is closed, bridge the operating pressure switch cables temporarily and switch on the voltage to the heat pump again. if the compressor now starts in auto or in manual test there might be a fault in the operating pressure switch, replace the .
If the two temperatures are close together, it does not require much work, but if they are far apart, it is harder to pump the heat Q outside, i.e. it takes more work. If T c = 300K (or about 81 o F) and the outside air is at T h = 310K (about 99 o F), it takes at least 33J of work to pump 1000J of heat …
May 28, 2008· My York heat pump at my house stopped putting out cold air. The Status Lamp fault code says "High discharge pressure". I tried googling this phrase to see what it means but the couple of hits on topic were indecipherable to a layman. Turned the …

As an MCS accredited installer and manufacturer, Kensa works as a partner with many installers, self-builders, specifiers and housing providers to deliver exceptionally well-designed ground source heat pump systems which out-perform the market.
Typically, ground source heat pumps produce between three and five units of heat for every unit of electricity consumed, representing a ScoP of 3 – 5 (or between 300% and 500% efficiency). By comparison, a traditional boiler might have an efficiency of between 60% and 90%.
Nov 29, 2011· We have a climate-master Ultra Classic Geo-thermal heat pump which we have just upgraded (the water source to) with a very expensive high efficiency variable frequency pressure pump and control kit. D … read more

Troubleshooting Guide Alarm high pressure The operating pressure switch does not open but the heat pump opens at high pressure Action: Check that the operating pressure switch opens at the correct pressure, using manometer apparatus. If the high pressure switch opens at a lower pressure than indicated there is a fault in the high pressure switch
10 Steps to Servicing a Geothermal Heat Pump Sonny Hamton | Jun 01, 2011 A geothermal heating and cooling system uses a geothermal or ground-source heat pump and a loop system to extract heat from the earth and carry it to a home in the winter.
SYS-APM010-EN Water-Source and Ground-Source Heat Pump Systems 1 Overview of a Water-Source Heat Pump System In a typical water-source heat pump (WSHP) system, each zone has a dedicated WSHP that cools or heats air to maintain the desired temperature in that zone. A WSHP contains all the components of a refrigeration circuit, including one or
Waterfurnace geothermal high pressure lockout. kygeo Posts: 2 Member. . high pressure light still comes up and shuts it down. So I shorted the high pressure switch again (ground loop pump still running while wired separately). Voila. I have cooling. . A compressor in a geo heat pump is a pretty big ticket item to leave to chance. If they .
Having problems with your ground source heat pump? Nu-Heat offer friendly on and offline support and resources to help you get to the core of the issue. . Motor protection alarm/Phase fault. . This could be high pressure in the refrigerant, caused by poor flow on the waterside of heat exchanger in the heat pump so it overheats. Things to .
High pressure switch failure: F9: Both pressure switch contacts are open at the same time: EA: Mis-wiring fault between FTC and Ecodan: EB: Mis-wiring fault between FTC and Ecodan: EC: Unit cannot finish start up process: U1: Ecodan high pressure fault: U2: Ecodan high compressor discharge temperature: U3: Ecodan discharge thermistor problem: U4
A ground source heat pump system can help to lower your carbon footprint as it uses a renewable, natural source of heat – the ground. According to the Energy Saving Trust, a heat pump with mid-range efficiency would save you most carbon when used to replace an old electric heating system (with storage heaters) or coal heating system.
Jan 18, 2015· Fix for low pressure in a geothermal ground loop Greg Anderson . I am running this Econar 5 ton ground source heat pump system in Southeast …
Feb 10, 2014· Home Forums > Geothermal Heat Pump Info > Maintenance and Troubleshooting > "Water Flow" status light - WaterFurnace Premier AT. . Upon investigating we see there's a direct water line plumbed into the ground loop using a pressure and one-way valve. I assume this is used to continuously keep pressure in the loop over the years.
Feb 14, 2014· 5 Ton water to water heat pump with buffer tank. Open loop. 12 GPM on source side. Been in operation for 2 years before any issues. Unit will run for about 25 minutes with high side pressure slowly creeping up until it hits 530 psi and trips the high limit switch. Low side pressure stays steady at 100 psi throughout the entire run time.
Rather than calling up your mechanic, and asking him to take a look, you should first consider doing some light spot-checks of your own, which can help you to find and fix most of the common problems which affect heat pumps, and a geothermal heat pump in particular. Troubleshooting your Heat Pump
A poorly designed and installed ground source heat pump system will, effectively, be heating a property on electricity alone, which is by far the most expensive solution on a unit-by-unit basis. So what are the common problems that befall GSHPs? 1. Slinkies. A slinky, in heat pump terms, is when the pipes that collect heat from the ground are coiled up repeatedly and wrapped over each other.
Jul 03, 2013· The most common ground source heat pump problems come from setting the output temperature. If you set your heat pump to generate hot water above 45 degrees, this will lower its performance. It will also increase your running costs.
