Engaging concept, right? Because a heat pump is more efficient than a gas heater at higher temperature levels, the dual fuel system defaults to a heatpump on milder days. Gas is more efficient for bigger heating loads, so the dual fuel system utilizes gas when temperature levels get really 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 fact - and this is just our opinion, mind you - the concern of "upgrading" to dual fuel heating equipment ought to in fact have less to do with expense and more to do with comfort.
Or not. Our team can assist you make an informed decision. Many double fuel systems are set up so that electrical power warms your home when the outside temperature is higher than 40 degrees. When it dips listed below 40 degrees, gas heat begins. The thinking is that it's overkill to warm your home with gas when things are "cold, however not that cold." Heatpump operate quite efficiently in those conditions, and utilizing gas really costs more.
In theory, it provides you the best of both worlds. However things are changing. In recent years, gas rates have taken a severe nosedive - types of heating system. Like it or not, fracking has made it much easier and more expense efficient to draw out natural gas from mother earth. The outcome for customers is that it's less expensive to warm your home with gas than at any other time in current memory, even when temperature levels exceed 40 degrees.
If your perception of heatpump is that they're painfully costly to operate in super-cold weather, you ought to get a load (pun meant) of what's on the marketplace today. In many cases, property owners with new heat pumps do not have to fret about costly "extra," "resistance," or "strip" heat laying waste to their electrical bills.
Even people in Vermont utilize electrical energy to warm their houses nowadays! Crazy, right? Here's what all of this indicates for double fuel heating: If you already have gas lines connected to your house, it may be more cost-efficient to stick with an all-gas heater. If you're changing an old heat pump, going with a modern-day, energy-efficient heatpump most likely makes more sense than double fuel.
So far, things aren't looking so great for double fuel any longer (types of heating system). If there the effectiveness gains aren't as fantastic as we believed, does double fuel still serve a function? We suggest dual fuel heat in this circumstance: Your home becomes exceptionally dry in the fall and winter, leaving you with annoyingly dry skin.
With gas, the temperature level of the air coming out of your vents will practically always be greater than your body temperature level. By contrast, heat produced by heat pumps often feels cool (heating unit). It isn't cool - it's warmer than the ambient temperature level - however it feels that way because your body temperature level is greater than the temperature level of the air produced by the heatpump.
Anyway, the result of gas's "truly hot" heat is that it dries out the air a lot more than a heatpump's "less hot" heat. Some individuals do not like this negative effects. If that sounds like you, dual fuel heating might make good sense. Here's a breakdown of heat source possibilities according to comfort concerns and A/C facilities: Take benefit of the gas lines you've got and opt for double fuel equipment.
However, if your dry skin has actually reached the level of overall cracked-skin misery, think about changing to a heat pump. If your home is linked to gas, go with an all-gas heating system. Currently utilizing a heat pump? Stick to that. It may be why the dryness isn't getting to you.
Natural gas, dual fuel, heatpump - whatever is just a lot better than it utilized to be! Whether you choose dual fuel or something else, simply make sure to element convenience into your decision. Various types of systems do produce various conditions inside your house. You're currently getting new, high quality devices, so effectiveness is more or less taken care of.
So, does double fuel heat make sense for your house? Just like the majority of things in life and in HVAC, it's up to you.
Most of North American homes depend on a central furnace to supply heat. A furnace works by blowing heated air through ducts that provide the warm air to spaces throughout your house via air signs up or grills. This type of heater is called a ducted warm-air or required warm-air distribution system.
Inside a gas- or oil-fired furnace, the fuel is blended with air and burned - heating systems. The flames heat a metal heat exchanger where the heat is moved to air. Air is pressed through the heat exchanger by the "air handler's" heater fan and then forced through the ductwork downstream of the heat exchanger (types of heating system).
Older "climatic" heating systems vented directly to the environment, and wasted about 30% of the fuel energy simply to keep the exhaust hot adequate to securely rise through the chimney. Present minimum-efficiency heating systems minimize this waste substantially by utilizing an "inducer" fan to pull the exhaust gases through the heat exchanger and cause draft in the chimney.
