    Dedicated Consumer Units for Heat Pump Installations

    Modern heat pump systems commonly use inverter-driven compressors and electronic control equipment. These systems can generate complex residual currents, meaning standard protection devices may not always be suitable.

    Heat Pump Consumer Units fitted with Type B, Type B HP or Type F RCD protection are designed to support renewable heating systems where enhanced residual current detection is required. Installing a dedicated board provides clear circuit separation, structured protection and simplified maintenance.

    RCD Protection for Inverter-Driven Heat Pumps

    Inverter-based heat pumps can produce AC, pulsating DC and, in certain fault conditions, smooth DC residual currents. For this reason, some manufacturers specify advanced RCD types.

    Type B RCD

    Detects AC, pulsating DC and smooth DC residual currents. Suitable for applications where DC leakage may be present.

    Type B HP RCD

    Designed specifically for heat pump applications, offering characteristics tailored to inverter-driven renewable heating systems.

    Type F RCD

    Provides enhanced protection compared to standard devices and is suitable for certain single-phase inverter loads.

    Always refer to the heat pump manufacturer’s installation instructions to confirm the correct RCD type for the system.

    Installation Considerations

    When selecting a heat pump consumer unit, installers should assess:

    • System load requirements

    • Supply type (single phase or three phase)

    • Manufacturer-specified RCD type

    • Circuit design and isolation requirements

    • Allowance for future system expansion

    Using a dedicated consumer unit with the correct RCD configuration supports safe operation, regulatory compliance and long-term system reliability.

    FAQs

    Do all heat pumps require Type B protection?
    Not necessarily. Some systems specify Type B, Type B HP or Type F protection depending on inverter design and manufacturer requirements.

    Why use a dedicated consumer unit for a heat pump?
    A dedicated unit provides appropriate protection, circuit separation and easier maintenance compared to integrating into an existing board.

    What is the difference between Type B and Type B HP?
    Type B HP devices are designed specifically for heat pump applications, while standard Type B devices provide broad DC residual current detection.

    Next Day Delivery

    Cut-Off Time and Order Information
    To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

    In Stock Delivery Policy

    Free Next-Day Delivery Over £100 + VAT:
    Orders above £100 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £200 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £200 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

    Backorder Delivery Policy

    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
