A little terminology, explained.
kW, kWh and kWp — what’s the difference?
kW describes power: how quickly energy is supplied or used. kWh describes an amount of energy: for example, a battery’s storage capacity. kWp describes a solar array’s rated peak output under standard test conditions. Battery power and capacity are different checks in your design.
Does “electric” mean “renewable”?
Solar PV generates renewable electricity. A heat pump moves heat from the environment using electricity. An electric boiler or water heater converts electricity directly into heat. Its carbon impact depends on the electricity used; these technologies have different efficiency and running-cost profiles.

Electric boilers & hot water
Built around your home.
Configured for the way you live.
SwiftHeat UK Group Ltd can plan electric boiler and hot-water arrangements around your existing heating system, the fabric of your property and the demands of your household.
We assess what can be retained, what needs upgrading and how the proposed system would operate. The right configuration follows the calculations and your priorities.
01 System boiler with an unvented cylinder
A suitable electric system or flow boiler can serve the heating and an appropriately matched indirect hot-water cylinder. We assess mains water flow and pressure, cylinder capacity, reheating time, available space and the safe discharge arrangement. This can be useful where stored hot water suits the household’s demand.
02 Electric combi arrangements
Consider an electric combi where its heating and hot-water performance match the home. Instantaneous models are limited by their electrical input and achievable hot-water flow; stored-water combi models have their own capacity and recovery limits. We check showers, baths and simultaneous use, rather than assuming a gas-combi replacement will perform identically.
03 Regular, open-vented heating systems
A manufacturer-approved electric heat-only or flow boiler may be suitable for an existing open-vented heating circuit. We assess the feed-and-expansion arrangement, pipework, pump, cylinder and controls. Where conversion to a sealed system is proposed, we first assess whether the existing installation is suitable. Not every electric boiler supports an open-vented system.
04 Heating with separate hot-water storage
Space heating and domestic hot water can be designed separately, for example with an electric flow boiler and a direct electric cylinder. We compare storage capacity, recovery, heat losses, available tariffs and compatible solar-diversion options. The value of storing heat is assessed alongside battery charging and electricity export.
05 Radiators, underfloor heating & multiple zones
Suitable designs can serve radiators, underfloor heating or a combination of both, including separately controlled areas. We assess room heat losses, water temperatures, flow rates, pumps, pipework and controls. Extensions, annexes and renovations are assessed within the property’s overall heating and electrical demands.
Need hot water only? Explore compact and stored-water solutions
Your design starts with:
- Property construction, insulation & ventilation
- Room-by-room heat-loss calculations
- Occupancy, comfort & hot-water demand
- Existing radiators, pipework & cylinders
- Electrical supply & simultaneous loads
- Installation cost, tariffs & ongoing care
Two separate design choices. A sealed or open-vented heating circuit describes the heating water system. An unvented or vented cylinder describes the domestic hot-water storage. We assess each arrangement and confirm compatibility.
Solar PV and a battery may contribute to an electric boiler’s electricity use. They do not remove its winter demand or make it equivalent to a heat pump. Your proposal compares the complete system, including imported electricity and likely running costs.

Electric hot-water solutions
Smaller spaces.
Specialist hot-water design.
SwiftHeat UK Group Ltd is experienced in designing and installing unvented electric hot-water storage systems, including compact solutions such as the Ariston Velis Evo range.
From a single sink to a flat, annexe or family home, we match the arrangement to the space and the people using it. Where gas is unavailable, electric hot water can operate independently of the property's space heating.
01 / A SINK OR WASHROOM
Hot water close
to where it's needed.
A small unvented store beneath or near a sink can serve suitable low-demand outlets. Shorter pipe runs can reduce waiting and distribution losses. We assess the number of outlets, frequency of use and recovery time.
Examples: Ariston Andris, Heatrae Sadia Hotflo, STIEBEL ELTRON SHC and Hyco Speedflow.
02 / A FLAT OR ANNEXE
Compact storage.
A considered fit.
A slim wall-mounted electric water heater can suit smaller homes or shower-room applications where its usable capacity meets demand. We check shower flow, consecutive use, available wall support and the time needed to reheat.
Example: Ariston Velis. Current ranges include Velis Pro and Velis Tech Wi-Fi; Velis Evo is a phase-out range.
03 / A HOUSEHOLD OR MORE OUTLETS
Stored hot water.
Sized for daily life.
A direct electric unvented cylinder can serve a wider hot-water demand without a gas boiler. We assess peak use, mains flow and pressure, usable storage, recovery and available space, including suitable slimline options.
Examples: Megaflo Eco Direct, Gledhill StainlessLite Plus Direct, Joule Cyclone Direct and OSO Super Xpress.
Instantaneous options, where suitable.
For suitable outlets, an instantaneous electric heater provides hot water without a storage cylinder. We check the achievable flow at the required temperature rise and the electrical load. Higher-demand models may require a three-phase supply.
Connected to a wider energy plan.
Where compatible, scheduled heating or solar-PV diversion can make use of suitable tariffs or surplus generation. We compare these with battery charging, export and heat-pump water heating. Controls must preserve safe water temperatures and reliable availability.
Explore established hot-water manufacturers Seven UK-market options
We consider product suitability, technical support, parts availability and warranty terms. This is a selection shortlist; the appropriate model and supply arrangements are confirmed in your proposal.

Designed around demand. Installed with care.
Discuss my hot-water needs Hot-water sizing starts with occupancy, outlets, draw-off patterns and recovery. Room-by-room heat-loss calculations separately establish space-heating demand. We assess the electrical supply, structure, water conditions, expansion and relief arrangements, discharge route, temperature control and maintenance access.
A smaller stored-water heater has a finite capacity. We explain what it can supply and how long it takes to recover, so the recommendation matches your expectations.

Your questions, answered
Make your next
step an informed one.
A good recommendation leaves room for your questions. Here are some of the things worth discussing before choosing a system.
Talk through my questionsCan my home become completely self-sufficient?
Greater independence is achievable for some homes, but complete year-round self-sufficiency is a different design challenge. Most domestic solar and battery systems retain a grid connection, particularly for winter. Your assessment should distinguish annual generation from the amount you can use when it is needed.
Could an electric boiler work with solar and a battery?
It can form part of a suitably designed electrical system, but available solar generation and battery power may not meet the boiler's demand. We check both electrical power and stored energy, alongside winter grid use. A direct electric boiler produces roughly one unit of heat per unit of electricity; a well-performing heat pump can deliver several. We compare likely running costs before recommending either.
Will a heat pump keep my home warm in winter?
A properly designed heat-pump system can heat a home through winter. Performance depends on the property, heating demand, outdoor conditions and system temperatures. Room-by-room heat-loss calculations and a review of radiators and controls help establish the appropriate design.
When would you recommend a hybrid heating system?
Where a detailed comparison supports combining a heat pump with a compatible boiler. The assessment considers comfort, installation constraints, energy prices, controls and future improvements. A fossil-fuel hybrid continues to use fuel and is not a net-zero heating system.
Are grants available for every option?
No. Eligibility depends on the property, technology, installer and current scheme rules. The Boiler Upgrade Scheme can support eligible heat-pump installations in England and Wales; fossil-fuel hybrid systems and direct electric boilers are not eligible technologies. We check the current position before including any grant in a proposal. Check current government guidance ↗︎
Will my energy bills definitely fall?
Savings depend on your starting point, installation, usage and tariffs. Your proposal should show estimated combined running costs, standing charges, maintenance and the assumptions behind the figures. We explain uncertainty so you can assess the investment realistically.
Can I make improvements over time?
Yes. A whole-home plan can sequence suitable improvements around your budget and existing equipment. We consider how each step fits with later changes, including future heating demand, electrical capacity and available roof space.
Who will install and look after my system?
Your written proposal names the design and installation team, relevant certification and aftercare responsibilities. See the assessment-to-handover journey.
How much disruption should I expect?
This depends on the technology and existing installation. Your proposal should explain access, equipment locations, any work to radiators or pipework, expected interruptions to heating or hot water and making good. The installation programme is agreed before work begins.
