Should I Turn My Water Heater Off At Night?

Having hot water for showers, washing dishes, and just everyday household tasks is brilliant. But hot water comes at a cost. Heating large amounts of water uses energy, and that ends up reflected in your bills. Here at Ninja Plumbers, your #1 plumber in Fulham, we often get asked whether it's worth turning your water heater off at night to save a few quid. Let's explore the options!

Is It a Good Idea?

The short answer is, maybe. The longer answer is that it depends on several factors:

Type of Water Heater: Do you have a storage tank heater or a newer, tankless system? Different systems have different efficiencies.
Insulation: Tank heaters lose heat over time. A well-insulated tank loses less heat, giving you better savings if you turn it off overnight.
Your Hot Water Needs: If you're an early riser who takes a shower first thing, you might not find much use in turning the heater off overnight.

Let's break it down a bit more.

Storage Tank Water Heaters

Storage tanks heat and store large amounts of water, using either gas or electricity. Even with insulation, they lose heat slowly over time. During the night, this unused hot water cools down in the tank. In the morning, the heater cycles on to bring it back up to temperature. While you might gain some efficiency by turning it off, if you wake up needing tons of hot water immediately, you might actually use more energy as it fires up to regain the lost heat.

Tankless Water Heaters

These units are becoming more popular in Fulham. They only heat water when you need it, eliminating the issue of standby heat loss. Turning them off won't save much energy at all. Your focus should be on good model selection and efficient usage as these generally cost a bit more to operate.

Should I Actually Turn Off My Water Heater?

Consider these points to help you decide:

  • Cost savings: Potential savings vary, but many homeowners save a bit if they have well-insulated tanks and don't have heavy morning usage.
  • Convenience: Be prepared for potentially cooler water in the morning or even having to wait while it reheats.
  • Safety: Electrical safety is crucial. If not comfortable doing it yourself, consult a plumber in Fulham for guidance. Gas water heaters can pose a danger; leave adjustments to qualified professionals.
Other Ideas for Savings

Here are some extra tips, on top of the switch-off debate, from your friends at Ninja Plumbers:

Lower the temperature: Often, water heaters are set higher than necessary. A slight adjustment downwards reduces energy use.
Fix Leaks: Even drips add up quickly! Get those faulty taps fixed ASAP.
Insulate: An insulating blanket around a tank, even a new one, works wonders and is usually DIY-friendly.
Upgrade: Old heaters are inherently less efficient. Consider if it's time for a replacement and seek advice from experts in heating services in Fulham.
