He’s currently working on delivering energy efficiency advice to local businesses through the ERDF funded BEST project www.best-ne.co.uk as well as delivering consultancy on energy storage and renewables to a variety of private and public sector clients. But they work in very different ways, and each have their own pros and cons. Compare the pros and cons. Since they do not use combustion to create heat, like gas furnaces do, they do not create any CO. Technically, gas furnaces produce more heat than heat pumps. Extremely hot air is not always a good thing, though. Heat pumps can actually be a better choice in certain regions, such as the South, where winters are milder. Ecoinvent is a not-for-profit organisation which provides an industry standard a database for Life Cycle Assessment purposes. There are a lot of opinions out there on whether you should install a heat pump vs. gas furnace. The best heat pump for you will depend on your type of home and your heating needs. Your email address will not be published. As before it can be assumed a gas boiler will run at 90% efficiency, so the cost per kWh of heating would be 0.0489 £/kWh. Installation costs vary considerably but in general a domestic air source heat pump based central heating system will cost at least twice as much to install as an equivalent gas central heating system. Do you have figures for a comparison with oil? Further analysis of the EST trial by DECC in March 2012 (Detailed analysis from the first phase of the Energy Saving Trust’s heat pump field trial) examined a number of these heat pump installations in more detail, paying particular attention to the factors that influence system performance. This gives us a climate change impact of 0.3760 kgCO2eq(GWP100)/kWh. Gas furnaces may provide overpowering heat when the temperatures outside are between 40 and 60 degrees. It is important to remember the Ecoinvent database includes everything, including the infrastructure of the CCGT. HomeAdvisor's Complete Heat Pump or Forced Air Furnace Guide defines the differences between electric and gas heat pumps and gas, electric, propane, and oil furnaces. Save my name, email, and website in this browser for the next time I comment. Looks like you are doing your very best to put people of…. Here are the top eight myths, and the truth behind them, of installing a heat pump vs. gas furnace so you can make an educated decision. The air handler has a coil and heat strips inside of it. It is a smaller air-source unit with an outdoor compressor/condenser and an indoor air-handling unit. If you disable this cookie, we will not be able to save your preferences. Consequently, some of the EST report data has been revised and Table 1 of the DECC report shows the mean system efficiency to be 1.82 for ASHP and 2.39 for Ground Source Heat Pumps (GSHP).

Narec Distributed Energy has carried out detailed monitoring of numerous air source heat pumps, and our results tally with those of the Energy Savings Trust, with values between 2.0 and 3.0, although the upper end is rare. Let’s think about this in more detail. Check out these eight myths about heat pumps vs. gas furnaces to gather the facts so you can decide which heating … Heat pumps can deliver several units of heat for every unit of electricity. Heat pumps and gas furnaces are two popular options for heating a home. Which elements of the blog were difficult? Heat pump vs furnace. While a heat pump works similarly to an air conditioner, a heat pump is not the same as an air conditioner. Go to the unit outside of your home. This means that every time you visit this website you will need to enable or disable cookies again. Most of the pumps use a liquid refrigerant as coolant, that is pumped into the underground pipes (in the case of a ground source heat pump) or into the external fan cover tubes (in the case of an air source heat pump), which absorbs the air or underground heat, that later is passed through a compressor where its further heated and moved to the heating and hot water circuits of the house.

The upfront cost for installing a heat pump is usually cheaper than the cost to install a furnace. They can also produce extremely hot heat, which means that the temperature in your home can quickly reach the setting on your thermostat. This would suggest that in order for the heat pump heating cost to be the same or better than gas, the SFP would be need to be 3.70. I enjoyed reading while going through this article and this is the best link for gaining all the information about it.Do visit this Comfortgroup.co.nz For vital information that can be used again by anyone. This ratio is often called the co-efficient of performance (COP) which tells us how wel… The air-to-air heat pump is the most common type of heat pump and works by moving the warm outside air to the inside of your home. They operate like refrigerators in reverse and normally have a fan to blow outside air over an evaporator heat exchanger. Seriously!? But they work in very different ways, and each have their own pros and cons. They operate like refrigerators in reverse and normally have a fan to blow outside air over an evaporator heat exchanger. Tom Bradley is a Life Cycle Assessment expert at Narec DE.

In most cases this would exceed the installation cost of the heat pump system including the oversized radiators that are needed to achieve high SPFs. The ‘mid-range’ ground source system efficiencies were between 2.3 and 2.5, with the highest figures above 3.0.

If you do not have gas lines leading to your home, then a gas furnace cannot be installed.
Air source heat pumps use electricity to generate heat much more efficiently than normal electric heaters. Also, if you don’t have natural gas lines running to your home, you have to have the gas lines installed in order to use a gas furnace, and this can be extremely expensive. The test also included ground source heat pumps, which has slightly higher measured system efficiencies than the air source heat pumps. From this article you will get to know about the air source heat pumps vs gas boiler. It appears some sites had anomalies in the data, for example boost heater energy consumption not measured, the contribution of an oil boiler being included in system heat and some data provided from a manufacturer rather than the EST monitoring system. If you live in an area where electricity costs less than gas, then a heat pump is also the better option. There are three types of heat pumps: air-to-air, ductless mini-split and geothermal. This article gives suggestions on limitations and delimitation of such selection. A heat pump can do both. What you need are facts. When the heat pump pulls the hot air from outside your home, it moves the air into an air handler that is on the inside unit of your home. © Copyright 2012-19: Narec Distributed Energy.

But that’s something of an oversimplification because air source heat pumps currently benefit from Renewable Heat Incentive (RHI) payments of 10.71p per kWh. An electrically powered compressor raises the temperature of the refrigerant and this heat is given up to a condenser inside the property. This means, for a heat pump to have a lower level of greenhouse gas emissions, it would need to have a SPF of over 1.72 in the UK. Alex Savidis is a renewable energy technical specialist at Narec DE. Since then it has dropped significantly.

Gas furnaces do produce CO, which can be harmful. I have a PHD in forensic science, fluent in 4 languages and THIS is what one has to encounter/reed AND understand to decide to invest/purchase air source heating!? INSTALLATION COST Generally, the initial cost and installation of a gas furnace is cheaper than a heat pump. This website uses cookies so that we can provide you with the best user experience possible. A gas furnace is not always the best way to heat a home. Air source heat pumps use electricity to generate heat much more efficiently than normal electric heaters. As 2.5 is a reasonable value for an SPF, then heat pumps can now be considered a better environmental choice than gas boilers. When this blog was originally written, according to the UK Government’s “2012 Guidelines to Defra / DECC’s GHG Conversion Factors for Company Reporting” the average value for greenhouse gasses emitted per kWh of electricity was 0.54702 kgCO2eq(GWP100)/kWh. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings. Given that we’ve already established Since the electricity industry was privatised, there has been a bewildering array of utility tariffs so it can be difficult to work out the relative running costs of gas boilers and heat pumps However, using figures from the UK Government we find an average direct debit electricity bill is based on £0.181/kWh whilst gas was  £0.044. As long as a heat pump has a SPF greater than 1 then it should be cheaper than direct electric heating. Your email address will not be published. This blog looks at how high the SPF needs to be for the heat pump to outperform a condensing gas boiler in terms of greenhouse gas emissions as well as running costs.

If we look at the “Greenhouse gas reporting: conversion factors 2019” we have a value of  kgCO2eq(GWP100)/kWh for Scope 2 emissions. If you live in a region where electricity is cheaper than gas, then a heat pump can be a more cost-effective and efficient way to heat your home. This is an update on a previous blog from the 24th of June 2013, updated to take account of developments with Air Source Heat Pumps and the decarbonsing of the UK electricity grid. For a detailed look at the performance of solar thermal, thermodynamic panels and Air Source Heat Pumps in relation to domestic hot water, please see  our discussion paper “COP Water Heating Technologies”, If you are interested in lab or in-situ monitoring of the COP of heat pumps, please email info@narecde.co.uk or call 01670 543 009.
