## What draws the most electricity in a house?

The most electricity-consuming appliance in an average household is usually the air conditioner or heater. These appliances require a large amount of energy to keep your home at a comfortable temperature.

Additionally, appliances like clothes washers, dryers, stoves, and dishwashers also draw a large amount of electricity. Electronics, such as televisions, computers, gaming consoles, and other home entertainment systems draw a substantial amount of energy as well.

Finally, lighting is also a big contributor to an average home’s electricity usage. Inefficient light bulbs, as well as over-lighting with too many lights, can cause a jump in a household’s electric bill.

## How do I calculate kWh for my house?

To calculate the kilowatt-hours (kWh) for your house, you’ll need to know the power usage of individual appliances and multiply it by the hours these appliances are used in a day. To start, you’ll want to make a list of all major appliances in your home and their wattage ratings (you can typically find this information in the manual or on the device itself).

Then, calculate the watts consumed by each appliance by multiplying its watts rating by the number of hours used per day. Finally, add up the watts for all of the appliances to calculate total per-day kWh usage.

For greater accuracy, you can also consider the electricity used while the appliance is turned off (such as standby energy consumption). To get the total kWh used in a month, multiply the per-day kWh usage by 30.

## Is it cheaper to leave heating on low all day?

Whether it is cheaper to leave your heating on low all day will depend on several factors, including the type of heating system in use, the size of your property and the outside temperature. If you have a traditional boiler with cast-iron radiators, for instance, the time it takes for the heated water to heat up the radiators will mean that leaving the heating on low all day is likely to be more expensive compared with running the heating for a set time each day.

On the other hand, if you have a modern boiler, such as a combi-boiler or a heat-only boiler, then it may be cheaper to leave your heating on low all day. With a modern boiler, you not only benefit from lower running costs but also a more efficient heating system.

In general, modern boilers heat up more quickly, meaning they don’t have to work as hard to heat up the radiators.

Furthermore, modern boilers typically use the most cost-effective fuel type of all: gas. So, in some cases, it could be cheaper to leave your heating on low all day, particularly if your home is well insulated and your boiler and radiators are efficient.

Ultimately, the most cost-effective approach to heating your home will depend on your unique circumstances. It is therefore recommended to speak with a heating expert who can assess your current and projected needs, and provide further guidance about the most energy- and cost-efficient solutions for your home.

## What size boiler do I need for a 3000 square foot home?
