Which one is better ? A water heater tank or a tankless water heater?


A water heater tank or a tankless water heater?

Answer: both tanks and tankless units are standardised and fully capable units of supplying residential hot water provided adequate: sizing, configuration, installation and tuning. However we need to shed some light on the ongoing battle of opinions about the benefits and risks in upgrading to a tankless water heater unit. 


Tankless water heaters use a relatively newer technology that has revolutionised the supply of hot water by eliminating the reservoir of hot water (tank). Hence they have the following advantages compared to a water heater tank: 

  • Significantly higher life expectancy : a water heater tank lasts an average of 10 year versus 20 years average lifespan of a tankless unit. 
  • Save space : much smaller, wall mounted units
  • Unlimited hot water: the tankless water heater never “runs out” of hot water as it heats water on demand instead of keeping a hot tank hence it never “runs out”. 
  • Government rebate: Installing a tankless hot water is endorsed and incentivised by the majority of gas providers in ontario and increases your amount and qualification rate for a Home Energy Rebate.

  • Sizing your hot water heater is very important especially in the case of tankless units, they come with different Flow rates over different models and sizing the unit too large or too small will definitely end up as a failure story. 
  • Upgrading to a tankless needs a complete assessment of your household’s hot water supplied units and water usage behaviour. 
  • Upgrading to a tankless hot water heater unit is an extensive job requiring a set of skills, endurance and experience. Our technicians have been educated and trained with the premiers of this industry in order to perform adequately.
  • Tankless water heaters require annual maintenance to ensure optimal efficiency and lifespan.
