Maximising Savings: Time-of-Use Tariffs for Efficient Air Source Heat Pumps

A Smarter Way to Heat Your Home with Heat Pump Load Shifting

Energy prices aren’t getting any kinder. You’re craving comfort without the shock of a massive bill. Enter heat pump load shifting: the art of timing your heating around cheap electricity. Couple that with a savvy time-of-use tariff and zero-carbon R290 refrigerant, and you’ve got a recipe for serious savings and a greener home.

In this guide, we’ll walk you through the what, why and how:

  • What is heat pump load shifting and why it matters.
  • How R290 technology supercharges efficiency.
  • Real-world impact backed by the latest research.
  • Practical steps: smart controls, grants, installation tips.

Why Time-of-Use Tariffs Matter for Air Source Heat Pumps

Time-of-use (ToU) tariffs switch prices throughout the day. Think off-peak, shoulder and peak slots. Your heat pump happily warms your home when electricity costs less. Less spend, more warmth.

With heat pump load shifting, you:

  • Avoid top-tier rates during evening peaks.
  • Maximise cheap overnight power.
  • Balance demand on the grid (helpers love that).

A recent NBER study found households slashed gas use by 90% after switching to a heat pump and saw a 61% rise in electricity. Overall, total energy demand dropped by 40%, and CO₂ emissions fell by 36% in just one year. Time-of-use tariffs halved electricity consumption during the evening peak. Load shifting works—even on the coldest days, across all building types.


The Basics of Heat Pump Load Shifting

Heat pump load shifting means running your heat pump when electricity is cheapest. It’s like charging your phone at night when the grid isn’t busy. Here’s how it breaks down:

  1. Off-Peak Comfort
    Your pump heats water or air overnight.
  2. Stored Warmth
    Insulated tanks or thermal mass hold heat.
  3. Peak-Time Savings
    Your home stays cosy without hefty peak charges.

These steps aren’t sci-fi. Smart thermostats and modern controllers handle the scheduling. No manual fiddling. You set your preferences, and the system learns your habits.


Benefits of R290 Refrigerant Technology

You’ve heard of eco-friendly heat pumps. R290 takes it further. It’s a zero-carbon refrigerant. That means:

  • Lower Global Warming Potential
    Up to 99% reduction versus older refrigerants.
  • Higher Efficiency
    Better heat transfer, less electricity used.
  • Future-Proof
    Aligns with upcoming eco-regulations.

Pair R290 units with heat pump load shifting and you get a double win: reduced carbon footprint plus wallet-friendly energy bills.


Implementing Load Shifting in Your Home

Smart Controls and Scheduling

Modern thermostats are your best friend. They can:

  • Auto-adapt to ToU tariffs.
  • Track local weather forecasts.
  • Learn your routines and tweak settings.

They talk to your heat pump. You talk to your phone. It’s that simple.

Government Grants and Finance Options

Installing an air source heat pump can be more affordable with grants. In the UK, schemes like the Boiler Upgrade Scheme offer rebates up to £5,000. Combine that with:

  • Low-rate finance
  • Flexible payment plans

and you’ll see how heat pump load shifting pays for itself faster.

Around this point, if you’re itching to optimise your home’s heating, Start heat pump load shifting savings with our expert team


Looking at the UK market, heat pumps hit a $1.56 billion size in 2023. They’re growing at 11.5% annually to 2030. Why? People want sustainability and cost control.

From the NBER paper:

  • 68% average lifetime emissions savings per heat pump.
  • Peak consumption cut in half with a tailored ToU tariff.
  • Public subsidy returns £1.24 for every £1 spent.

That’s not wishful thinking. It’s data. You get real savings, cut carbon, and help stabilise the grid.


Overcoming Common Challenges

Managing Upfront Costs

Yes, a heat pump investment is higher than a boiler. But:

  • Grants slash the sticker price.
  • Finance spreads payments.
  • Load shifting multiplies savings.

Ensuring Long-Term Performance

Regular maintenance keeps your system humming. Megawave’s service plans include:

  • Annual health checks
  • Prompt repairs
  • AI-assisted performance monitoring

Because a well-tuned pump shifts loads more efficiently.
