Yes, you can absolutely replace your storage tank for an instant gas hot water system. However, because the instant gas hot water system has to heat the water much quicker they need a lot more gas when they are operating, because of this we would need to upgrade the gas supply to the hot water system to ensure it operates safely and efficiently.
When an instant gas hot water system is heating it uses significantly more gas than a storage tank as it needs to heat the water much faster. However, in the long run they use much less gas as they only heat the water as you need it instead of always trying to maintain the temperature in a tank.
In most cases we are able to have a gas supply installed at your property. We would install a gas meter box on the front of your house and then ATCO gas would arrange to bring in the gas supply, from there we are able to run gas pipework internal of your property and install a gas hot water system and any other gas appliances. This may not be available in certain areas or in apartment buildings, but we are more than happy to come out to your property and discuss your options, free of charge!
No, Instant gas hot water systems are very cheap to run all year round as they only heat the water as you need it. Because gas is relatively cheap they are generally much cheaper than electric hot water systems.
