Water heaters in Portland, ME, are a crucial component of modern living. They’re also a significant factor in household expenses. The Department of Energy estimates water heating accounts for 18% of the average household’s energy usage. This is one reason customers are contacting us at Dog House to switch to tankless water heaters. On-demand systems can lower water-heater-related energy consumption by over 30%.
Always can count on your customer service to help me maintain my heating system. They do an exceptional job and always keep me informed. Great teamwork.
Traditional tank water heaters remain the most popular solution. You can choose an electric unit or a system that burns fuel, such as natural gas, liquid propane, or fuel oil. The tank size for the typical household is 40 – 50 gallons. There are 10 – 20-gallon tanks for smaller households and 75 – 120-gallon tanks for larger households.
A condensing water heater is a type of high-efficiency fuel-burning water heater. An even more efficient approach is the heat pump water heater. These have a tank but use a heat pump as opposed to a traditional heat exchanger. There are also hybrid heat pump systems. Those use the heat pump to heat the water most of the time. They switch to a traditional heat exchanger during periods of high demand.
Tankless water heaters are between traditional and heat pump systems in terms of efficiency. There are both condensing and non-condensing systems. The big advantage here is that these systems don’t store water. They heat it on demand. That means that if you size them accurately, you’ll enjoy a practically unlimited supply of hot water.
All water heaters require routine maintenance, typically once a year. For storage-based systems, we recommend flushing the tank. Doing so removes sediment and limescale to improve efficiency and extend the life of the system. Our plumber will also check the sacrificial anode rod and replace it as needed.
Tankless water heaters require descaling. Limescale can build up on valves, on the heat exchanger, and in tubes and pipes. If you have hard water, you may need to descale the system twice a year. As an alternative, you could have us install an anti-scale device.

I am so happy I called the Dog House when my furnace stopped working properly. Their customer service was impeccable and everyone was so friendly. The techs called before they arrived and were extremely polite, helpful and friendly. They were able to diagnose the issue with my furnace and replace the part all in one visit. I would definitely use them again and recommend them!
