Disclaimer: I am not an electrician: you should exercise due diligence before proceding! **Q: Can this item replace an old 'horstmann e7 bx' unit?** A: I used it as a direct replacement for an existing 30 year old Horstmann E7 unit but I can’t say whether it was a ‘bx’ unit. **Q: Does anyone know if this unit will replace an old Electra tech control panel? I only need to use it for setting the hot water not radiators** A: I don't know if it will replace 'an old Electra tech control panel' but you can certainly set this unit for water heating only for any chosen time period/duration with summer/winter auto time change.There is also a Boost selector for use at anytime outside your 'set' period. Hope it helps!! **Q: Can i replace my old horstmann electronic 7 with this** A: You can replace an old Horstmann electronic 7 with the new model. It fits directly into the existing backplate fittings. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***F on 18 January 2018* ### ⭐⭐⭐⭐⭐ Review *by A***R on 16 April 2024* ### ⭐⭐⭐⭐⭐ Review *by K***G on 19 July 2022* ## Frequently Bought Together - Horstmann Electronic 7 Water Heater, Multi - Heatrae Sadia 95612599 Spare Type TSE Thermostat 11" Rod - Albion SU034 Spare RTS-3 Immersion Thermostat --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/50701200-horstmann-electronic-7-water-heater-multi](https://www.desertcart.ae/products/50701200-horstmann-electronic-7-water-heater-multi) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-13*
