Determining if a water heater is large enough for a bathtub is actually pretty simple; the water heater tank should be about 2/3 the size of the bathtub. For example, if you have a 40-gallon water heater, it would be just large enough for a 60-gallon bathtub.
Finally, for applications with a bathtub, either Ariston's 80-litre Velis Evo Wi-Fi or 100-litre Pro1 Eco are recommended; as the average bath holds 80 litres of water (with at least 75% being hot) a large capacity unit is required – especially if it will be required to supply other outlets, such as a kitchen sink, at ...

Oversized water heaters consume more energy than properly sized models, so your utility costs are noticeably higher. Plus, bigger models are more expensive upfront, so you've also wasted money on the initial equipment purchase. The same goes for tankless water heaters that are too big – they waste energy and money.
The average bathtub capacity ranges from 40 to 70 gallons of water, and if the tub is constructed for a small corner area, it will be near the lower end of that range, typically around 40 gallons. A clawfoot tub typically holds 40 to 60 gallons of water, but a modern freestanding tub carries 60 to 76 gallons.
The energy needed to heat the water to run an 80-litre bath at 42C, on the other hand, will cost you 81p, more than three times the cost of a shower. An eight-minute shower using an electric shower will also use around 40 litres of water, half that required to fill a bath.
A rule of thumb is you'll need a water heater tank that's at least 2/3 the size of your bath tub. Most walk-in tubs range in capacity from 42 to 60 gallons. So, for a 60 gallon walk-in tub, you'd need at least a 40-gallon water heater.

On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
A broken or burned-out heating element (immersion) could be the culprit for cold water in the hot water tap. As we use our water heater, the heating element gets worn out over time, which reduces its efficiency and lowers the maximum water temperature, until it completely stops heating the water.
