Systems for the Hot Water You Need
In the Hamilton and Niagara regions, water heaters are essential in people’s homes. They provide the hot water you need for bathing, cleaning, cooking, and other daily tasks. That is why Lancaster Heating and Cooling offers the most energy-efficient water heating systems on the market.
The Importance of the Right Water Heater – Tankless vs. Storage
As their name implies, storage water heaters heat the water slowly and store it in a tank for later use.
Tankless systems heat water directly without using a storage tank. Turning on the hot water tap sends cold water through a pipe into the heating unit. The water is heated by a natural gas burner or an electric element, providing an immediate supply of hot water on demand.
Storage Water Heaters

Tank water heaters offer families affordability, dependable hot water that is pre-heated and stored, and are ideal for high-demand households.
Tankless Water Heaters

Ideal for homes with high hot water needs and/or limited installation space, tankless water heaters offer you an endless source of hot water.

What Our Clients Say About Our Water Heater Service
“Much appreciation to the Lancaster team. My water heater sprang a leak at a most inopportune time. It was during the hottest period of the summer so far. Although they were extremely busy with A/C calls, Richard was able to schedule us in quickly and the team of Mark, Ben, Wes and Andrew responded with an excellent installation of a new tankless hot water system. They were very professional and did an excellent job under less than ideal circumstances. Thank you” – David Williams, Google, July 2025

Water Heater FAQs
What is the most common problem with a water heater?
The most common problem with water heaters is that the water tank produces too little hot water. Usually, this can be solved by turning up the temperature on the tank’s thermostat. Be careful, however, not to turn the temperature up too high, as this can produce scalding hot water.
