Engaging concept, right? Since a heat pump is more effective than a gas heating system at higher temperature levels, the dual fuel system defaults to a heat pump on milder days. Natural gas is more efficient for larger heating loads, so the dual fuel system uses gas when temperature levels get actually low.
So would we. Reality, however, is a bit more complicated. Nowadays, dual fuel isn't always more energy efficient than its most popular options for every house all of the time. In reality - and this is just our opinion, mind you - the concern of "updating" to double fuel heating equipment ought to in fact have less to do with expense and more to do with convenience.
Or not. Our team can help you make a notified choice. The majority of double fuel systems are set up so that electrical energy heats your house when the outside temperature level is greater than 40 degrees. When it dips below 40 degrees, gas heat starts. The thinking is that it's overkill to heat your house with gas when things are "cold, but not that cold." Heat pumps operate quite efficiently in those conditions, and using gas really costs more.
In theory, it gives you the best of both worlds. However things are altering. In the last few years, gas rates have taken a major nosedive - heating system. Like it or not, fracking has made it much easier and more expense efficient to draw out gas from mom earth. The outcome for customers is that it's cheaper to warm your home with gas than at any other time in recent memory, even when temperature levels exceed 40 degrees.
If your perception of heat pumps is that they're painfully expensive to operate in super-cold weather, you ought to get a load (pun planned) of what's on the marketplace today. For the most part, house owners with new heat pumps don't need to stress over costly "supplemental," "resistance," or "strip" heat desolating their electrical expenses.
Even people in Vermont use electricity to warm their homes nowadays! Crazy, right? Here's what all of this implies for double fuel heating: If you currently have gas lines connected to your house, it may be more economical to stick to an all-gas heating system. If you're changing an old heatpump, going with a modern, energy-efficient heatpump probably makes more sense than double fuel.
Up until now, things aren't looking so excellent for double fuel anymore (types of heating systems). If there the performance gains aren't as fantastic as we believed, does double fuel still serve a function? We recommend double fuel heat in this situation: Your home ends up being extremely dry in the fall and winter season, leaving you with uncomfortably dry skin.
With gas, the temperature of the air coming out of your vents will usually be higher than your body temperature. By contrast, heat produced by heatpump in some cases feels cool (types of heating system). It isn't cool - it's warmer than the ambient temperature level - however it feels that method due to the fact that your body temperature is higher than the temperature level of the air produced by the heat pump.
Anyway, the outcome of natural gas's "truly hot" heat is that it dries out the air a lot more than a heatpump's "less hot" heat. Some people don't like this negative effects. If that sounds like you, dual fuel heating may make good sense. Here's a breakdown of heat source possibilities according to comfort issues and HEATING AND COOLING facilities: Make the most of the gas lines you have actually got and go with dual fuel equipment.
Nevertheless, if your dry skin has reached the level of total cracked-skin torment, think about switching to a heat pump. If your home is connected to natural gas, choose an all-gas heating system. Presently using a heat pump? Stick with that. It may be why the dryness isn't getting to you.
Natural gas, double fuel, heat pump - everything is just a lot better than it used to be! Whether you go with double fuel or something else, just be sure to aspect convenience into your decision. Various kinds of systems do produce different conditions inside your house. You're currently getting new, high quality equipment, so efficiency is basically taken care of.
So, does dual fuel heat make sense for your home? Just like a lot of things in life and in HEATING AND COOLING, it depends on you.
Most of North American households depend upon a central heating system to offer heat. A furnace works by blowing heated air through ducts that deliver the warm air to spaces throughout your house via air registers or grills. This kind of heating system is called a ducted warm-air or forced warm-air circulation system.
Inside a gas- or oil-fired heating system, the fuel is mixed with air and burned - heating system. The flames heat a metal heat exchanger where the heat is transferred to air. Air is pushed through the heat exchanger by the "air handler's" heater fan and after that forced through the ductwork downstream of the heat exchanger (home heating).
Older "atmospheric" heating systems vented directly to the atmosphere, and lost about 30% of the fuel energy just to keep the exhaust hot adequate to securely rise through the chimney. Current minimum-efficiency furnaces reduce this waste significantly by utilizing an "inducer" fan to pull the exhaust gases through the heat exchanger and induce draft in the chimney.
