If you’re still using storage heaters in your home, you’ve probably wondered:

“Is it finally time to upgrade?”

We get this type question a lot — especially in older properties, flats, or homes that aren’t on the gas grid. So in this guide, we’ll break down the pros, cons, costs, and what to consider if you’re thinking about switching to a more modern heating setup.

What Are Storage Heaters?

Storage heaters use off-peak electricity (usually on an Economy 7 tariff) to “charge up” overnight, then slowly release heat during the day.

Sounds clever, right? And back in the day, it was — especially before central heating was widespread.

But fast forward to 2025, and the story’s changed a bit.

Pros of Storage Heaters (Still Worth Knowing)

• Use cheaper overnight electricity (if you’re on the right tariff)

• No pipework or boiler required

• Simple, low-maintenance setup

• Can be a fit for flats or rural homes with no gas

But Here’s the Catch

We see the same pain points from customers time and again:

• Lack of control – You charge them the night before, so if the weather turns mild, you waste heat.

• Inconsistent warmth – Rooms often feel too warm in the morning and cold by evening.

• Limited smart features – Most older units can’t be zoned, timed properly, or integrated into smart home systems.

• Cost creep – Electric-only heating is still more expensive than modern gas or hybrid systems (unless you’ve got solar).

And the biggest one?

“We just can’t get comfortable. One room’s roasting, the other’s freezing.”

What Are the Alternatives?

Here’s what we’re fitting for homeowners around Exeter who are replacing storage heaters:

1. Modern Electric Panel Heaters

• On-demand heat

• Programmable & controllable via app

• Ideal for smaller properties or where gas isn’t available
  Still runs on electric, so costs can add up without careful use

2. Air Source Heat Pumps

• Super efficient (especially in well-insulated homes)

• Works with underfloor heating or radiators

• Long-term savings and eligible for government incentives
  Higher upfront cost, needs outdoor space

3. Traditional Wet Central Heating (Gas or Electric Boiler)

• Full control over temperatures and timings

• Can combine with smart thermostats

• Great for larger homes or those switching from night storage

We’ve upgraded dozens of homes from storage heaters to a modern boiler system, and the difference in comfort (and control) is night and day.

What Does It Cost to Switch?

Prices vary depending on your home and system choice. As a rough guide for 2025:

Upgrade TypeTypical Cost Range

Modern electric panel heaters (3-bed)£1,500–£3,000

Wet heating system (gas or electric)£4,000–£6,500

Air source heat pump system£7,500–£12,000+

So… Should You Replace Yours?

Here’s a good rule of thumb:

If your storage heaters are 15+ years old, and you're finding them expensive or uncomfortable — yes, it’s worth considering an upgrade.

Especially if:

• You’re renovating or improving insulation

• You want more control over your heating

• You’re planning to stay in your home long-term
