Gas Heat Pump Air Conditioning System (GHP) GHP function and benefits Yanmar Gas Heat Pump (GHP) air conditioning systems provide high efficiency and cost effective heating and cooling solutions for buildings using gas. Being mainly powered by gas, these GHP systems can give low running costs, reduced CO2 emissions and eliminate the need for expensive electricity supply upgrades that are often required by electrically powered heat pump systems. They can also reduce seasonal overloading of electricity grids, create new opportunities for gas to be used for cooling and also help to stabilize the demand for gas and electricity over the year. GHP operation and key features GHP systems operate by using energy from gas to power a gas-engine which then drives the heat pump. The heat pump transfers large amounts of heat energy between the building and the outside air; this heat transfer is done between indoor units fitted in the building and an outdoor unit installed outside the building.

Heat transfer with the outside air is done using heat exchangers built into the outdoor unit so no other heat source or heat sink construction is required, this with the small footprint and quiet operation of GHP systems means that GHP systems can be installed in a huge variety of locations. The gas-engine used in Yanmar GHP systems is an example of Yanmar’s own lean-burn gas engine technology which provides a world-class combination of efficiency and reliability. hide ac unit insideSince engine heat can be reclaimed and used for additional heating GHP systems have particularly high efficiency in heating mode, this also means that these heat pump systems still have high heating output even with low outdoor air temperatures.what gauge wire for ac unit With a wide range of indoor unit options, these Yanmar GHP air-conditioning systems offer precise control and great flexibility to ensure all year comfort in all kinds of applications.what gauge wire for ac unit

Yanmar GHP systems are ideal for restaurants, shops, showrooms as well as hotels, office buildings, schools, care-centers, sports clubs, factories and a multitude of other applications. Remote Monitoring Service Login Page（GHP/CP） Gas Heat Pump Air Conditioning System (GHP) Inquiries and SupportShould you use natural gas heating rather than a heat pump in your home? Some say the interest in heat pumps is fueled by irrational exuberance. Others say that because they require supplemental heat, heat pump performance is not acceptable. Another group says you'll get a better HERS Index by using gas heat. So how's a person to decide? Some of the folks who say these things are smart, established, and well respected in the HVAC and energy efficiency communities. The first answer to the lead question in this article is yes, it may be better for you to use natural gas heating in your home. The second answer is no, you might be better off with an electric heat pump. You also can reverse the order.

In other words, the best answer is, it depends. The truth is that anyone who says never or always is usually wrong, especially when it comes to which products, materials, or technologies to use in your home. In the case of gas heating versus heat pumps, here are some of the issues you need to consider: It doesn't make a lot of sense to put in a gas furnace in Valdosta, Georgia or Phoenix, Arizona. Where cooling loads dominate, heat pumps do, too. The further north you go, the more gas heat you find. That's changing, though, because building enclosures are getting better (more airtight and better insulated) and because we have better heat pumps. Climate zone does matter, but the one-size-fits-all approach is becoming obsolete, even when applied to specific climate zones. I've seen heat pumps in Maine and furnaces in Florida. Within a single climate zone, it may make the most sense to put in a gas furnace in one location and a heat pump in another. Natural gas rates have been really low for a few years now, but that hasn't killed the electric heat pump.

Look at Georgia, for example. Since deregulation of the gas industry here in the '90s, we typically pay about $30 per month in service charges. I've known people with gas heat and electric water heaters who get gas bills in the summer showing no gas consumption and an amount due of $30 or so. One of the problems with comparing the cost of operating a gas furnace to an electric heat pump is that you're billed for each in different units. You pay the gas company for how many therms you use and the electic utility for kilowatt-hours. Then you've got to factor in the efficiency of the furnace. If you really want to know which is cheaper, you've got to do the conversions and find out how many cents per Btu you pay for each fuel, with the equipment efficiency factored in. A more comprehensive analysis also would factor in the lifetime and maintenance costs of the different types of equipment. Still, with rates, efficiencies, and equipment costs all over the map, you can't make any generalization about always using heat pumps or always using gas heat.

As Kai Ryssdal does every day on MarketPlace, you've got to 'do the numbers.' If you're concerned about the environment, then you'd want to know something about the sources of your various fuel options. Natural gas has its fracking problems. Most electricity is generating by burning coal or natural gas. If you live in the Pacific Northwest, most of your electricity comes from hydropower, which is much cleaner but has disrupted river ecosystems and salmon runs. Building a net zero energy home? If so, that makes heat pumps more attractive because the source energy issue isn't as big a deal, but it also depends on the array of incentives available to you to make the onsite power production feasible. David Butler wrote a two-part series on the challenges of heating and cooling high-performance homes for us a couple of years ago. The first article was titled Just Say No to Furnaces in High Performance Homes and made the case that...well, do I really need to say? The second article, Heat Pumps and Hydronics – A Great Team for High Performance Homes, laid out a path for using heat pumps in a way that overcomes one of their biggest drawbacks: electric resistance heat to supplement the heat pump at low temperatures.

Yes, most heat pumps need supplemental heat. That certainly doesn't make them unacceptable, though. It means you need to be smart about how you set them up and use them. As David described in his second article, using a hydronic coil with heat from a water heater is a much better option for supplemental heat than is electric resistance heat. You really should click to read the article. Heat pumps today aren't the same as the early models from the 1970s and '80s. They've got the supplemental heat thing figured out. And they come in a wide variety of efficiency, capacity, and technology, from the standard models to mini-splits to ground-source heat pumps. Of course, furnaces (and boilers) have come along, too. We now have high-efficiency, sealed combustion furnaces that can distribute the heat through either forced air or hydronics. You can get a modulating condensing (mod-con) furnace that can adjust the capacity closer to the needs of the house. Overall, it's easier and less expensive to get a heat pump small enough to match the loads of a high performance home than it is to get an appropriately sized furnace.
